MC74F1245中文资料摩托罗拉数据手册PDF规格书

The MC74F1245 contains eight noninverting bidirectional buffers with 3-state outputs and is intended for bus-oriented applications. Current sinking capability is 24 mA at the A ports and 64 mA at the B ports. 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; Receive (active LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a high-Z condition.

• Noninverting Buffers

• Bidirectional Data Path

• B Outputs Sink 64 mA

• High Impedance Inputs for Reduced Loading

• Same Function and Pinout as the F245

• ESD Protection > 4000 Volts
