CD74HCT4543 Datasheet BCD-TO-7 SEGMENT LATCH/DECODER/DRIVER

Manufacturer: Texas Instruments

General Description

/ordering information The CD74HCT4543 high-speed silicon-gate is a BCD-to-7 segment latch/decoder/driver designed primarily for directly driving liquid-crystal displays.

While the latch enable (LD) is low, the latches are enabled to store the BCD inputs.

When the latch enable is high, the latches are disabled, making the outputs transparent to the BCD inputs.
