ON Semiconductor MC74HCT373ADWR2G Octal Transparent Latch

The MC74HCT373ADWR2G from ON Semiconductor is a high-performance, octal transparent latch with three-state outputs designed to be used in a wide range of digital applications. This integrated circuit is part of the high-speed CMOS HCT family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

This device features eight latches with three-state outputs for bus-organized systems applications. The MC74HCT373ADWR2G is compatible with LSTTL outputs and has the capability to drive 15 LSTTL loads. The octal transparent latch operates at a voltage range of 4.5V to 5.5V, which makes it suitable for interfacing with 5V logic systems.

The transparent latches are D-type flip-flops that feature a latch enable (LE) and output enable (OE) input. When LE is held high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs will be latched at the levels set up at the D inputs. Furthermore, a high on OE causes the outputs to assume a high impedance OFF-state, which is essential when connecting multiple outputs to a common bus line.

The MC74HCT373ADWR2G is offered in a wide-body SOIC-20 package, ensuring a compact footprint that is ideal for space-constrained applications. Its package is characterized for operation from -55°C to 125°C, which guarantees reliable performance across a broad range of temperatures, making it suitable for industrial applications.
