Renesas Electronics Corporation Buffers, Drivers, Receivers, Transceivers 74FCT245ATQG

The 74FCT245ATQG is a fast CMOS octal bidirectional transceiver designed for asynchronous two-way communication between data buses. It features low input and output leakage of 1¬µA maximum and operates at CMOS power levels, ensuring compatibility with true TTL logic levels, with typical output high voltage (VOH) of 3.3V and output low voltage (VOL) of 0.3V. The device supports high drive outputs, capable of sourcing -15mA and sinking 64mA, making it suitable for applications requiring robust data transmission. This transceiver complies with military standards, specifically MIL-STD-883, Class B, and is available in various package types including SOIC, SSOP, QSOP, TSSOP for industrial applications, and CERDIP, LCC for military applications. The output enable feature allows for "live insertion" by disabling both A and B ports when activated. The operational temperature range is from -40¬8C to +85¬8C for industrial and -55¬8C to +125¬8C for military grades, making it versatile for different environmental conditions.
