Latches

MM74HCT373N Description

The MM74HCT373N from onsemi is a high-speed octal transparent latch with 3-state outputs, designed for bus-oriented applications. This D-type latch features eight latches with a common output enable (OE) and latch enable (LE) control, allowing for efficient data storage and transfer. Operating within a 4.5V to 5.5V supply range, it is compatible with HCT logic levels, ensuring seamless integration into mixed-voltage systems. The device offers a propagation delay of 25ns and balanced output current of 7.2mA (both high and low), making it suitable for high-performance digital systems. Packaged in a 20-pin DIP (Dual In-line Package), it is ideal for through-hole mounting in prototyping and industrial applications.

MM74HCT373N Features

• Octal Transparent Latches: Eight D-type latches with 3-state outputs for bus interfacing.
• Wide Voltage Range: Operates at 4.5V–5.5V, compatible with TTL and CMOS logic levels.
