The SN74AS373DWR is an octal transparent D-type latch designed for applications requiring high-capacity or low-impedance load driving. It features eight latches in a single package with 3-state outputs, making it suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. 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 logic levels present at the D inputs. A buffered output-enable (OE) input can place the outputs in a high-impedance state, allowing for bus line driving without significant loading. The device operates within a supply voltage range of 4.5V to 5.5V and supports a temperature range of 0¬8C to 70¬8C. The SN74AS373DWR is available in a 20-pin SOIC package, making it a compact solution for various digital logic applications.
