The SN74F573 is an octal transparent D-type latch featuring 3-state outputs, designed for driving capacitive or low-impedance loads. It includes eight latches that operate in a transparent mode when the latch enable (LE) input is high, allowing the Q outputs to follow the D inputs. When LE is low, the outputs retain the last data state. The device also incorporates a buffered output enable (OE) input, which can place the outputs in a high-impedance state, facilitating bus driving without additional interface components. This latch is characterized for operation from 0¬8C to 70¬8C and supports a supply voltage range of 4.5V to 5.5V. The SN74F573 can handle output currents of up to 48 mA and is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers. The device is available in various package options, including plastic small-outline packages and standard plastic DIP configurations.
