TC74VCX573FK Datasheet Low-Voltage Octal D-Type Latch

Manufacturer: Toshiba

Overview: TC74VCX573FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX573FT, TC74VCX573FK Low-Voltage Octal D-Type Latch with 3.6 V Tolerant Inputs and Outputs The TC74VCX573 is a high performance CMOS octal D-type latch which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. This 8 bit D-type latch is controlled by a latch enable input (LE) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge.
