Description
 The TDS.51.. series are 13 mm character seven segment LED displays in a very compact package.
The displays are designed for a viewing distance up to 7 meters and available in four bright colors.
The grey package surface and the evenly lighted untinted segments provide an optimum on-off contrast.
All displays are categorized in luminous intensity groups.
That allows users to assemble displays with uniform appearence.
Typical applications include instruments, panel meters, point-of-sale terminals and household equipment.

Features
* Evenly lighted segments
* Grey package surface
* Untinted segments

General Description
The CD4511BC BCD-to-seven segment latch/decoder/driver is constructed with complementary MOS (CMOS) enhancement mode devices and NPN bipolar output drivers in a single monolithic structure. The circuit provides the functions of a 4-bit storage latch, an 8421 BCD-to-seven segment decoder, and an output drive capability. Lamp test (LT), blanking (BI), and latch enable (LE) inputs are used to test the display, to turn-off or pulse modulate the brightness of the display, and to store a BCD code, respectively. It can be used with seven-segment light emitting diodes (LED), incandescent, fluorescent, gas discharge, or liquid crystal readouts either directly or indirectly.
 Applications include instrument (e.g., counter, DVM, etc.) display driver, computer/calculator display driver, cockpit display driver, and various clock, watch, and timer uses.

Features
* Low logic circuit power dissipation
* High current sourcing outputs (up to 25 mA)
* Latch storage of code
* Blanking input
* Lamp test provision
* Readout blanking on all illegal input combinations
* Lamp intensity modulation capability
* Time share (multiplexing) facility
* Equivalent to Motorola MC14511

The SN54 /74LS48 is a BCD to 7-Segment Decoder consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers provide lamp test, blanking input/rippleblanking input for the LS48.
The circuit accepts 4-bit binary-coded-decimal (BCD) and, depending on the state of the auxiliary inputs, decodes this data to drive other components.
The relative positive logic output levels, as well as conditions required at the auxiliary inputs, are shown in the truth tables.
The LS48 circuit incorporates automatic leading and/ or trailing edge zero-blanking control (RBI and RBO). Lamp Test (LT) may be activated any time when the BI/RBO node is HIGH. Both devices contain an overriding blanking input (BI) which can be used to control the lamp intensity by varying the frequency and duty cycle of the BI input signal or to inhibit the outputs.

• Lamp Intensity Modulation Capability (BI/RBO)
• Internal Pull-Ups Eliminate Need for External Resistors
• Input Clamp Diodes Eliminate High-Speed Termination Effects
