74F1245

Features:

• Same function and pinout as 74F245
• High impedance NPN base inputs for reduced loading (70mA 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 74F1245 features an Output Enable (OE) input for easy cascading and Transmit/Receive (T/R) input for direction control. The 3-State outputs, B0B7, have been designed to prevent output bus loading if the power is removed from the device.
