STMicroelectronics M74HCT373B1R Octal D-Type Latch

The M74HCT373B1R is a high-speed CMOS octal D-type latch manufactured by STMicroelectronics, designed to integrate seamlessly into a wide array of digital systems. This integrated circuit (IC) is particularly well-suited for applications that require the temporary storage of data, allowing the data to be held stable and read out even after the input has changed.

With its advanced silicon-gate CMOS technology, the M74HCT373B1R offers the robustness and performance required for today's electronic devices. It ensures a high degree of compatibility with TTL outputs, thanks to its input switching levels which allow for direct interfacing with TTL logic levels. This makes the M74HCT373B1R an ideal choice for mixed-technology environments where both CMOS and TTL devices coexist.

The device features eight D-type latches with three-state non-inverting outputs for bus organized systems. The flip-flop is set or reset by the state of the D input (data) when the Latch Enable (LE) input is high. When LE is low, the output will be retained at the level it was set to prior, effectively 'latching' the data. The Output Enable (OE) input, when low, allows the data from the latches to be outputted. When OE is high, the outputs are in a high impedance state, which is particularly useful for sharing bus lines in a system without causing conflicts.

Key features of the M74HCT373B1R include:

• High-speed operation: Tpd = 15 ns (typical) at Vcc = 5V
• Low power consumption: Icc = 4 μA (max) at Ta = 25°C
• Compatible with bus-oriented systems due to its three-state outputs
• Pin and function compatible with 74 series
• ESD performance: HBM > 2 kV, MM > 200 V

Offered in a DIP20 package, the M74HCT373B1R provides a compact solution for implementing latches in your digital designs. Whether it's used in personal computers, communication devices, or complex automation systems, this IC delivers reliable, high-performance latching functions that designers can trust.

As with all STMicroelectronics products, the M74HCT373B1R is designed to meet the rigorous standards of the electronics industry, ensuring both quality and durability for your electronic projects.
