SN74LS373N Description

Short technical summary and product information.

The SN74LS373N is an octal transparent latch IC manufactured by Texas Instruments, designed for bus-organized system applications. It features eight latches with 3-state outputs, allowing for efficient bus interfacing. The device operates with a supply voltage range of 4.75V to 5.25V and has an operating ambient temperature range of 0°C to 70°C.

 

Key electrical characteristics include a maximum output current of 24mA for low states and -2.6mA for high states, with a typical propagation delay of 12ns. The latch enable input has hysteresis for improved noise margin, and input clamp diodes help limit high-speed termination effects. The SN74LS373N is available in a 20-pin PDIP package suitable for through-hole mounting.

 

This component is particularly useful for implementing buffer registers, I/O ports, and bidirectional bus drivers. Its 3-state outputs are designed to drive highly capacitive or low-impedance loads directly, without the need for external interface or pullup components.
