74F245PC

The 74F245PC from Texas Instruments is an octal bidirectional transceiver featuring non-inverting buffers and 3-STATE outputs, making it suitable for bus-oriented applications. This device facilitates bidirectional data flow, controlled by the Transmit/Receive (T/R) input. The A ports have a current sinking capability of 24mA, while the B ports can sink up to 64mA. The Output Enable (OE) input, when HIGH, places both A and B ports into a High-Z state, effectively disabling them.

This transceiver is available in a 20-lead Plastic Dual-In-Line Package (PDIP), designed for through-hole mounting. The device is RoHS3 Compliant and Lead Free per JEDEC: J-STD-020B standard. Its design ensures efficient data transfer in systems requiring bus interfacing and signal control.

Key electrical characteristics include the distinct current sinking capabilities at the A and B ports, providing flexibility in driving different loads. The 3-STATE outputs allow for multiple devices to share a common bus without contention when enabled. The T/R input logic determines the direction of data flow, enabling transmission from A to B (active HIGH) or reception from B to A (active LOW).
