INTEGRATED CIRCUITS 74F1245 Octal transceiver (3-State) Product specification IC15 Data Handbook 1995 Mar 01 Philips Semiconductors Philips Semiconductors Product specification Octal transceiver (3-State) 74F1245 FEATURES Same function and pinout as 74F245 High impedance NPN base inputs for reduced loading (70µA in Low and High states) DESCRIPTION The 74F1245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both transmit and receive directions. The B port outputs are capable of sinking 64mA and sourcing up to 15mA, producing very good capacitive drive characteristics. The device features an Output Enable (OE) input for easy cascading and Transmit/Receive (T/R) input for direction control. The 3-State outputs, B0–B7, have been designed to prevent output bus loading if the power is removed from the device. Useful in applications where light loading bus loading or direct interface with output of a MOS microprocessor is desired Octal bidirectional bus interface Glitch free during 3-State power up and power down 3-State buffer outputs sink 64mA and source 15mA TYPE 74F1245 TYPICAL PROPAGATION DELAY 5.0ns TYPICAL SUPPLY CURRENT (TOTAL) 115mA ORDERING INFORMATION DESCRIPTION 20-Pin Plastic DIP 20-Pin Plastic SOL COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C N74F1245N N74F1245D DRAWING NUMBER SOT146-1 SOT163-1 INPUT AND OUTPUT LOADING AND FAN-OUT TABLE PINS A0–A7, B0–B7 OE T/R A0–A7 B0–B7 DESCRIPTION A and B port inputs ...
