MC74LVX259DTG

The MC74LVX259DTG from ON Semiconductor is an 8-bit addressable latch fabricated with silicon gate CMOS technology. This device functions as a 1-of-8 decoder and is suitable for general-purpose storage applications in digital systems.

Key electrical characteristics include an operating voltage range of 2V to 3.6V and a typical propagation delay of 7.0 ns at 3.3V, with a listed delay time of 8ns. It consumes low power, with a quiescent current of 4mA and a low power dissipation of 2 µA maximum at 25°C. The device offers high noise immunity with input thresholds at 28% of VCC and provides protection for inputs and outputs.

This latch features four modes of operation: addressable latch, memory, one-of-eight decoding/demultiplexing, and reset. It is designed to interface 5.0V circuits to 3.0V circuits. The MC74LVX259DTG is available in a 16-TSSOP surface mount package, measuring 0.173 inches (4.40mm) in width.

Additional features include LSTTL-compatible inputs, balanced propagation delays, and pin compatibility with other standard logic families. It also boasts latchup performance exceeding 300 mA and robust ESD protection.
