Brand: Generic
SKU: 0-3993900
Price: 47 INR
Availability: InStock

CD4543 is a BCD-to-seven segment latch/decoder/driver designed primarily for liquid-crystal display (LCD) applications. It is also capable of driving light emitting diode (LED), incandescent, gas-discharge, and fluorescent displays. This device is functionally similar to and serves as direct replacement for the CD4056 when pin 7 is connected to VSS. It differs from the CD4056B in that it has a display blanking capability instead of a level-shifting function and requires only one power supply. When the CD4056 is used in the level shifting mode, two power supplies are required. When the CD4543 is used for LCD applications, a square wave must be applied to the PHASE input and the backplane of the LCD device. For LED applications a logic 1 is required at the PHASE input for common-cathode devices; a logic 0 is required for common-anode devices (see truth table). The CD4543B is supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Features:-

Display blanking of all illegal input combinations
Latch storage of code
Capability of driving two low power TTL loads, two HTL loads, or one low power Schottky load over the full rated-temperature range
Pin-for-pin replacement for the CD4056B (with pin 7 tied to V _SS )
Direct LED driving capability
100% tested for quiescent current at 20 V
Maximum input current of 1 ÂµA at 18 V over full package-temperature range; 100 nA at 18 V and 25Â°C
Noise margin (full package-temperature range) =
