Low-Voltage Octal D-Type Latch with 5-V Tolerant Inputs and Outputs
The TC74LCX373F/FW/FT is a high-performance CMOS octal
D-type latch. Designed for use in 3.3-V systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
The device is designed for low-voltage (3.3 V) VCC applications,
but it could be used to interface to 5-V supply environment for
both inputs and outputs.
This 8 bit D-type latch is controlled by a latch enable input
(LE) and a 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.
Note: xxxFW (JEDEC SOP) is not available in
Japan.

Note 11: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption.
Average operating current can be obtained by the equation:
ICC (opr) = CPD･VCC･fIN + ICC/8 (per bit)
