CD74HC4543
Overview
Input Latches for BCD Code Storage Blanking Capability Phase Input for Complementing Outputs Wide Operating Temperature Range . . . -55oC to 125oC Balanced Propagation Delay and Transition Times Significant Power Reduction Compared to LSTTL Logic ICs The CD74HC4543 high-speed silicon-gate device is a BCD to 7-segment latch/decoder/driver designed primarily for directly driving liquid-crystal displays. It has an active-high disable input (LD), an active-high blanking input (BI) and a phase input (PH) to which a square wave is applied for liquid-crystal applications.
