The SN74ALS563BNSR is an 8-bit D-type transparent latch featuring 3-state outputs, designed for driving high-capacitance or low-impedance loads. It is suitable for applications such as buffer registers, I/O ports, bidirectional bus drivers, and working registers. The latch-enable (LE) input allows the Q outputs to follow the complements of the data (D) inputs while LE is high. When LE is low, the outputs are latched at the inverse of the D inputs. A buffered output-enable (OE) input controls the outputs, allowing them to be placed in a high-impedance state, which does not load or drive the bus lines significantly. This feature enables the device to drive bus lines without additional interface or pullup components. The SN74ALS563BNSR operates within a supply voltage range of 4.5V to 5.5V and has a temperature range of 0¬8C to 70¬8C. It is available in a 20-pin SOP package.
