onsemi Voltage Level Translator Latch 1 TTL/NMOS, Surface Mount 20-Pin SOIC MC74HCT573ADWG

onsemi MC74HCT573ADWG is a voltage level translator latch IC designed primarily for use in electronic systems requiring interface between TTL or NMOS outputs and high-speed CMOS inputs. This device is implemented with high-performance silicon-gate CMOS technology, ensuring low power consumption and improved propagation delays.

The device operates bi-directionally and comes in a 20-pin SOIC surface mount package, facilitating easy integration into modern PCB designs. With an operating voltage range of 4.5 to 5.5 V, it supports standard logic levels compatible with TTL and CMOS families. The latch functionality features a transparent mode when latch enable is high, and stable data retention once the latch enable goes low, meeting setup and hold time requirements.

It features a three-state output type with an output enable pin that forces outputs into a high-impedance state when activated, allowing multiple devices to share a common bus. The maximum propagation delay time is 45 nanoseconds at a load capacitance of 15 pF, supporting high-speed logic applications.

This IC operates reliably over a broad temperature range from -55°C to 125°C, making it suitable for industrial, manufacturing, laboratory, and embedded system applications. Its output drive capability supports 15 LSTTL loads, enabling effective interfacing with downstream logic circuits.

The compact dimensions of 12.95 mm length and 2.4 mm height in the SOIC package allow efficient PCB usage. The chip contains 234 field-effect transistors (FETs) or 58.5 equivalent logic gates, indicative of its high integration and functionality.
