MM54HC4511 Datasheet Bcd-to-7 Segment Latch/decoder/driver

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: MM54HC4511 MM74HC4511 BCD-to-7 Segment Latch Decoder Driver January 1988 MM54HC4511 MM74HC4511 BCD-to-7 Segment Latch Decoder.

General Description

This high speed latch decoder driver utilizes advanced silicon-gate CMOS technology It has the high noise immunity and low power consumption of standard CMOS integrated circuits as well as the ability to drive 10 LS-TTL loads 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 (Bl) 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 puter calculator display driver cockpit display driver and various clock watch and timer uses The 54HC 74HC logic family is speed function and pinout patible with the standard 54LS 74LS logic family All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground
