CD74HCT4543 Datasheet (Texas Instruments) - BCD-TO-7 SEGMENT LATCH/DECODER/DRIVER

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

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 ar
