Description
The TC74VHC9541 is an ultra-high-speed octal Schmitt buffer fabricated using silicon-gate CMOS technology. The TC74VHC9541 combines low power consumption of CMOS with Schottky TTL speeds.
The outputs can be put in the high-impedance state by placing a logic HIGH on the Enable (G) input. The CONT input determines the logical inversion of data. A logic LOW on the CONT input configures the TC74VHC9541 as an inverter; a logic HIGH on the CONT input configures the TC74VHC9541 as a buffer.
All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHC9541 is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity.
Additionally, all the inputs have a newly developed protection circuit without a diode returned to VCC. This enables the inputs to be tolerant of up to 5 volts even when power supply is down. The input power-down protection capability makes the TC74VHC9541 ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to 3 V and battery back-up circuits.

Features
*High speed: tpd = 5.0 ns (typ.) (VCC = 5 V)
*Low supply current: ICC = 4 μA (max) (Ta = 25°C)
*High noise immunity: VNIH = VNIL = 28% VCC (min)
*All inputs are provided with power-down protection.
*Symmetrical rise and fall delays: tpLH ≈ tpHL
*Wide operating voltage range: VCC (opr) = 2 to 5.5 V
*Pin-compatible with TC74VHC540 and TC74VHC541

General Description
These octal 3-STATE bus drivers are designed to provide the designer with flexibility in implementing a bus interface with memory, microprocessor, or communication systems.
The output 3-STATE gating control is organized into two separate groups of four buffers. The DM74ALS240A control inputs symmetrically enable the respective outputs when set logic LOW, while the DM74ALS241A has complementary enable gating. The 3-STATE circuitry contains feature that maintains the buffer outputs in 3-STATE (high impedance state) during power supply ramp-up or rampdown.
This eliminates bus glitching problems that arise during power-up and power-down.

Features
* Advanced low power oxide-isolated ion-implanted Schottky TTL process
* Functional and pin compatible with the DM74LS counterpart
* Improved switching performance with less power dissipation compared with the DM74LS counterpart
* Switching response specified into 500W and 50 pF load
* Switching response specifications guaranteed over full temperature and VCC supply range
* PNP input design reduces input loading
* Low level drive current: 74ALS = 24 mA

DESCRIPTION
The M54HC374 is an high speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS
NON INVERTING fabricated with sub-micron silicon gate C2MOS technology.
This 8 bit D-TYPE FLIP FLOP is controlled by a clock input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q outputs will be set to the logic state that were
setup at the D inputs.
While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while OE is high the outputs will be in a high impedance state.
The output control does not affect the internal operation of flip-flops; that is, the old data can be
retained or the new data can be entered even while the outputs are off.
All inputs are equipped with protection circuits against static discharge and transient excess
voltage.

General Description
 The VHCT374A is an advanced high speed CMOS octal flip-flop with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CP) and an output enable input (OE). When the OE input is HIGH, the eight outputs are in a high impedance state.

 Protection circuits ensure that 0V to 7V can be applied to the input and output
(1) pins without regard to the supply voltage. This device can be used to interface 3V to 5V
systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
Note:
