The DM74ALS245AN from Texas Instruments is an advanced, low-power Schottky octal bus transceiver. This device features 8 pairs of 3-STATE logic elements designed for memory, microprocessor systems, and asynchronous bidirectional data buses. Communication between buses is controlled by the DIR input, allowing data to transmit from the A bus to the B bus or vice versa. The enable input (G) can disable both driver and receiver outputs, placing them in a high-impedance state to effectively isolate the buses.
Key electrical specifications include a supply voltage range of 4.5V to 5.5V and an operating temperature range of 0°C to 70°C. The transceiver offers 3-STATE outputs that are independently controlled on the A and B buses. It is specified for switching response into 500 Ohm / 50 pF and can interface with CMOS at VOH = VCC - 2V. The device utilizes PNP inputs to reduce input loading and guarantees switching specifications over the full temperature and VCC range.
Packaged in a 20-PDIP format, the DM74ALS245AN is designed for through-hole mounting. Its non-inverting logic output and glitch-free bus operation during power up and down make it suitable for various digital system applications requiring reliable data transfer and bus isolation.
