MC74F1245 Datasheet | Motorola Semiconductor

MC74F1245 OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3-STATE INPUTS/OUTPUTS The MC74F1245 contains eight noninverting bidirectional buffers with 3-state outputs and is intended for bus-oriented applications. Current sinking capability is 24 m A at the A ports and 64 m A 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 m A - High Impedance Inputs for Reduced Loading - Same Function and Pinout as the F245 - ESD Protection > 4000 Volts PIN ASSIGNMENT VCC OE 20 19 B0 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 20 1 OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3-STATE INPUTS/OUTPUTS FAST™ SCHOTTKY TTL 20 1 J SUFFIX CERAMIC CASE 732-03 N SUFFIX PLASTIC CASE 738-03 20 1 DW SUFFIX SOIC CASE 751D-03 1 T/R 2 A0 3 A1 4 A2 5 A3 6 A4 7 A5 8 A6 9 A7 10 GND LOGIC SYMBOL 2 3 4 5 6 7 8 9 ORDERING INFORMATION MC74FXXXXJ Ceramic MC74FXXXXN Plastic MC74FXXXXDW SOIC A0 A1 A2 A3 A4 A5 A6 A7 19 1 OE T/R B0 B1 B2 B3 B4 B5 B6 B7 18 17 16 15 14 13 12 11 GUARANTEED OPERATING RANGES Symbol VCC TA IOH IOL IOH IOL Parameter DC Supply Voltage Operating Ambient Temperature Range Output Current  High Output Current  Low Output Current  High Output Current  Low An Outputs An Outputs Bn Outputs Bn Outputs 74 74 74 74 74 74 Min 4.5 0 - - - - Typ 5.0 25 - - - - Max 5.5 70 - 3.0 24 - 15 64 Unit V °C m A m A m A m...
