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.

*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

The TD74BC574P/TD74BC574F is a high-speed 8-bit flip-flop fabricated with silicon gate Bi-CMOS technology. It achieves the high-speed operation equivalent to the FAST family while
maintaining the Bi-CMOS low-power dissipation. The TD74BC574P/F is a non-inverting flip-flop. Each bit is individually controlled by a clock input (CK) and an output enable input (OE). When the OE input is high, all eight outputs are in the high-impedance state, which facilitates the interface with bus lines. All inputs are equipped with resistors and diodes to protect
against Electrostatic Discharge (ESD).

• High-speed operation ........................ tpd = 8.8 ns (typ.)
• Symmetrical output impedance ....... IOH = −3 mA (max) IOL = 24 A (max)
