Octal transceiver (3-State)
Product specification
74F1245
FEATURES
Same function and pinout as 74F245
High impedance NPN base inputs for reduced loading (70µA in
Low and High states)
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

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.
