SN74LS173AN Description

Short technical summary and product information.

The SN74LS173AN from Texas Instruments is a 4-bit D-type register designed for digital logic applications. This component features 3-state outputs, allowing direct interface with system buses without additional components. It offers gated output-control lines for enabling or disabling the outputs.

 

The register operates with a clock frequency of up to 35 MHz and requires a supply voltage between 4.75V and 5.25V. The maximum propagation delay is 30ns at 5V with a 45pF load. It has a supply current of 24 mA and an IOL of 24 mA, with an IOH of -2.6 mA.

 

Designed for a wide operating temperature range of 0°C to 70°C, the SN74LS173AN is suitable for various environmental conditions. It is packaged in a 16-PDIP through-hole configuration, with a package size of 16-DIP (0.300", 7.62mm). This device is ideal for applications requiring bus buffer registers and parallel load capabilities.
