74FCT245

FEATURES Function, Pinout and Drive Compatible with the FCT and F Logic FCT-A speed at 4.9ns max (MIL) Output levels compatible with TTL and CMOS Edge-rate control circuitry for significantly improved noise characteristics ESD protection exceeds 2000V P54FCT245/74fct245 OCTAL TRANSCEIVER WITH 3-STATE OUTPUTS Power-off disable feature Matched rise and fall times Fully compatible with TTL input and output logic levels 48 mA sink current, 12 mA source current (MIL) DESCRIPTION The P54/74FCT245 contains eight non-inverting bidirectional buffers with 3-state outputs and is intended for bus oriented applications. The transmit/receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active HIGH) enables data from A ports to B ports, and receive (active LOW) from B ports to A ports. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in a High-Z condition. Functional Block Diagram Pin Confi...
