Texas Instruments SN54ALS573C Octal D-type Transparent Latches With 3-State Outputs SNJ54ALS573CW

The SN54ALS573C is an octal 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 outputs to respond to data inputs while high, and when low, the outputs retain the last set data. A buffered output-enable (OE) input can place the outputs in a high-impedance state, allowing for bus line driving without significant loading. This device operates over a military temperature range of -55¬8C to 125¬8C, making it suitable for harsh environments. It supports a supply voltage range of 4.5V to 5.5V and offers various package options, including plastic small-outline and ceramic chip carriers. The SN54ALS573C is characterized by true logic outputs and a bus-structured pinout, enhancing its versatility in digital circuit applications.
