SN74LS145DR Description

Short technical summary and product information.

The SN74LS145DR is a monolithic BCD-to-decimal decoder/driver from Texas Instruments, designed for use as indicator/relay drivers or open-collector logic-circuit drivers. It consists of eight inverters and ten four-input NAND gates, with inverters connected in pairs to make BCD input data available for decoding.

 

This device offers full decoding of valid BCD input logic, ensuring all outputs remain off for invalid binary input conditions. It features high-performance, n-p-n output transistors capable of sinking up to 80 milliamperes of current. The inputs and outputs are compatible with TTL or DTL logic circuits, and outputs can interface with most MOS integrated circuits. The SN74LS145DR operates with a single supply voltage between 4.75V and 5.25V and has a typical power dissipation of 35 mW. It is supplied in a 16-SOIC package for surface mount applications.

 

Each input represents one Series 54/74 or Series 54LS/74LS standard load. The high-breakdown output transistors (15 volts) enhance its utility in various driving applications.
