TC74VCX16373FT_07

TC74VCX16373FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16373FT Low-Voltage 16-Bit D-Type Latch with 3.6-V Tolerant Inputs and Outputs The TC74VCX16373FT is a high-performance CMOS 16-bit D-type latch. Designed for use in 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 overvoltage tolerant inputs and outputs up to 3.6 V. This 16-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE) which are common to each byte. It can be used as two 8-bit latches or one 16-bit latch. When the OE input is high, the outputs are in a high-impedance state. All inputs are equipped with protection circuits against static discharge. Weight: 0.25 g (typ.)
