The SN54ALS373A is an octal D-type transparent latch featuring 3-state outputs, designed for driving high-capacitance or low-impedance loads. It includes eight latches in a single package, allowing for full parallel access for loading. The latch-enable (LE) input allows the Q outputs to follow the D inputs while LE is high, and when LE is low, the outputs are latched at the current D input levels. A buffered output-enable (OE) input can place the outputs in a high-impedance state, enabling the device to drive bus lines without significant loading. The device operates within a supply voltage range of 4.5V to 5.5V and supports a temperature range from -55¬8C to 125¬8C, making it suitable for various applications, including buffer registers and I/O ports. The SN54ALS373A is available in multiple package types, including the CF and J packages.
