Product Summary

The CD4543 is a BCD-to-seven segment latch/decoder/driver designed primarily for liquid-crystal display applicaitons. The CD4543 is also capable of driving light emitting diode, incandescent, gas-discharge, and fluorescent displays. The applications are instrument display driver, dashboard dislay driver, computer/calculator display driver and timing device driver.

Parametrics

CD4543 absolute maximum ratings: (1)DC supply voltage range, VDD: -0.5 to 20V; (2)input voltage range, all inputs: -0.5 to VDD+0.5V; (3)DC input current, any one input: ±10mA; (4)power dissipation per package, PD: 500mW; (5)operating temeprature range, TA: -55 to 125℃; (6)lead temeprature: 265℃.

Features

CD4543 features: (1)display blanking of all illegal input combinations; (2)latch storage of code; (3)capability of driving two low power TTL loads, tow HTL loads, or one low power schottky load over the full rated-temperature range; (4)pin-for-pin replacement for the CD4056B; (5)direct LED driving capbility.
