Logic range upgrades performance of legacy systems

Offered as a performance upgrade for legacy 5V TTL systems, the new range of logic devices from Diodes is based on an advanced CMOS process and is said to provide switching and power efficiency advantages over alternative technologies.

The 74AHCT1Gxx series operates from 4.5 to 5V and is optimised for general purpose control applications in a range of consumer electronic products. Nine logic functions have been announced in a choice of SOT25 and SOT353 packages and comprise AND, NAND, OR, NOR, XOR, inverter, Schmitt trigger inverter and tri state buffers. Diodes claims the single gate devices can bring routing and board space benefits to new builds, with logic functions able to be located at the precise point of application. The devices also integrate input hysteresis to improve susceptibility to noise.
