SN74LS145D Description

Short technical summary and product information.

The SN74LS145D from Texas Instruments is a monolithic BCD-to-decimal decoder/driver. This integrated circuit consists of eight inverters and ten four-input NAND gates, enabling full decoding of valid BCD input logic. All outputs remain off for invalid binary input conditions.

 

Key electrical characteristics include a single supply voltage range of 4.75V to 5.25V and a sink current capability of 80mA. The device operates within a temperature range of 0°C to 70°C. Its low power dissipation is typically 35mW.

 

Designed for indicator or relay driving, the SN74LS145D features high-performance n-p-n output transistors with a 15-volt breakdown. The outputs are compatible with most MOS integrated circuits, and inputs are compatible with TTL or DTL logic circuits.

 

This decoder/driver comes in a 16-SOIC package, suitable for surface mount assembly. Its 1x4:10 circuit configuration makes it suitable for various digital logic applications requiring BCD decoding and driving.
