Diodes Inc. has added standard shift register and decoder logic ICs to its enhanced 74HC, 74HCT, 74AHC and 74AHCT CMOS logic families.

Based on Diodes' updated 5V CMOS process, the 595, 594 and 138 logic functions offer improvements over industry-standard alternatives in terms of power-to-performance ratio and ESD protection, making them suitable for smart domestic appliances, data communication, and residential and industrial control applications.

The 8bit shift register with 8bit storage register (with and without tri-state outputs) and 3-to-8 line decoder are direct drop-in replacements for industry-standard logic devices, and are available in a choice of SO-16 and TSSOP-16 packages.

With a wide 2.0V to 5.5V operating voltage range, the logic parts are suitable for an array of uses, including 5V legacy systems. Additionally, the input hysteresis of the 24 new devices makes them less susceptible to problems of slow rising or falling data signals.
