SN74LS373N Description

Short technical summary and product information.

The SN74LS373N is an octal transparent latch IC featuring 3-state outputs, making it suitable for bus-organized system applications. When the Latch Enable (LE) is HIGH, the outputs transparently follow the data inputs. When LE is LOW, the data meeting setup times is latched. Data is available on the bus when Output Enable (OE) is LOW; OE HIGH places the bus output in a high impedance state.

 

This device operates within a guaranteed supply voltage range of 4.75V to 5.25V, with a typical value of 5.0V. The operating ambient temperature range is from 0°C to 70°C. It supports a maximum clock frequency of 35MHz and offers an output current of -2.6mA for high states and 24mA for low states.

 

The SN74LS373N is available in PDIP-20 and SOIC-20 packages. The PDIP-20 package is supplied in boxes of 1440 units, while the SOIC-20 package is available on tape and reel with 2500 units per reel. Its input clamp diodes help limit high-speed termination effects, and the latch enable input includes hysteresis for improved noise margin.
