New logic range upgrades performance of legacy systems
Diodes Incorporated has introduced a range of logic devices designed to provide a performance upgrade for legacy 5 V TTL systems. Based on an advanced CMOS process offering switching and power efficiency advantages compared with alternative technologies, the 74AHCT1Gxx devices serve as TTL compatible drop-in replacements for existing bipolar or CMOS parts.
Operating from 4.5 V to 5 V and delivering an output drive current of 8 mA, the 74AHCT1Gxx logic range will suit general-purpose control applications in a broad 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.
As single gate devices the 74AHCT1Gxx logic functions can also bring routing and board space benefits to new builds, with logic functions able to be located at the precise point of application. To improve susceptibility to noise, the devices have also integrated input hysteresis.
The 74AHCT1Gxx logic devices are priced from $0.08 each in 10k piece quantities.
