Texas Instruments SN74HCT645N is an eight-bit bus transceiver designed for asynchronous bidirectional communication, capable of transferring data between data
buses. The chip operates in a voltage range of 4.5V to 5.5V, has a high-current tristate output, and is capable of driving up to 15 LSTTL loads with low power consumption
and a maximum static current of 80µA. The SN74HCT645N uses TTL voltage compatible inputs, has an output drive capability of ±6mA, low input current (up to 1µA), and
a typical propagation delay of 14ns.
SN74HCT645N Transceiver Features:
- Supports asynchronous bidirectional communication, data can be transferred from bus A to bus B, or vice versa.
- Has an Output Enable (OE) input that can be used to disable the device, effectively isolating the bus.
- Low power design for applications requiring energy saving.
- Compatible with TTL voltage, simplified connection with other logic circuits.
SN74HCT645N Applications:
SN74HCT645N is widely used in data bus expansion and interface conversion, suitable for computers, communication equipment and various electronic systems,
especially in the need for high speed and low power consumption. Its design makes it ideal for data transmission and control in complex logic circuits.
