The 74HC573 from Nexperia is an octal D-type transparent latch featuring 3-state non-inverting outputs, making it ideal for bus-oriented applications. This device operates with a wide supply voltage range from 2.0 V to 6.0 V and is specified for operation across a temperature range of -40 °C to +125 °C.
The latch enable (LE) and output enable (OE) inputs control the device's functionality. When LE is HIGH, data at the inputs enters the latches, making them transparent. When LE transitions from HIGH to LOW, the latches store the input data present at the set-up time. A HIGH on the OE input forces the outputs into a high-impedance OFF-state, without affecting the latch's internal state.
This latch offers high noise immunity and CMOS low power dissipation. It is available in a TSSOP20 package, designed for surface mounting. The inputs include clamp diodes, allowing the use of current-limiting resistors for interfacing with voltages exceeding VCC. Its design makes it useful as an input or output port for microprocessors and microcomputers.
