HD74LS145

BCD-to-Decimal Decoder / Driver (with 15 V outputs)

REJ03D0436–0300

Rev.3.00

Jul.13.2005

This BCD-to-decimal decoder / driver consists of eight inverters and ten four-input NAND gates. The inverters are

connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid BCD

input logic ensures that all outputs remain off for all invalid binary input conditions. This decoder features high-

performance, n-p-n output transistors designed for use as indicator / relay drivers or as open-collector logic-circuit

drivers.
