ON Semiconductor MC74HC373ADTG Octal D-Type Latch

The MC74HC373ADTG from ON Semiconductor is a high-performance, octal D-type latch that is designed to interface directly with the high-speed switching characteristics of LSTTL and CMOS logic. This device is fabricated with silicon gate CMOS technology, which ensures low power consumption while maintaining high-speed operation.

This integrated circuit features eight latches with three-state outputs for bus-organized systems applications. Each latch is transparent, meaning that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is low, the data that meets the setup and hold time requirements on the D inputs is latched. The octal D-type latch is further equipped with an output enable (OE) input, which, when high, puts the outputs in a high-impedance state, allowing for interfacing with bus lines in a multi-master system.

The MC74HC373ADTG operates over a broad voltage range of 2V to 6V and offers a significant advantage in power and density for systems designers. ON Semiconductor's commitment to quality ensures that this device meets the stringent requirements necessary for use in a wide range of industrial and commercial applications.

Key features of the MC74HC373ADTG include:

• Eight latches in a single package
• Output drive capability of 15 LSTTL loads
• High noise immunity characteristic of CMOS devices
• Low power consumption: ICC = 4μA maximum at TA = 25°C
• Functionally compatible with the MC74HC373
• Pin and function compatible with the 74LS373

The device is provided in a TSSOP-20 package, which is designed for space-saving in PCB layouts and is ideal for surface-mount technology (SMT) processes. Whether you are working on data storage, buffer memory, or bus-oriented systems, the MC74HC373ADTG brings reliability and performance to your design.

ON Semiconductor's MC74HC373ADTG is an excellent choice for designers who require a latch that combines the low power characteristics of CMOS with the processing speed similar to LSTTL devices.
