74F2645 - Octal Bus Transceiver

Datasheet Summary

Description

This device is an octal bus transceiver designed for asynchronous two-way data flow between the A and B busses and is functionally equivalent to the 74F645.

The 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors.

Features

  • s 25Ω series resistors in the outputs eliminates the need for external resistors s Designed for asynchronous two-way data flow between busses s Outputs sink 12 mA and source 15 mA s Transmit/receive (T/R) input controls the direction of data flow s 74F2645 is a low power version of the 74F245 with 25Ω series resistors in the outputs Ordering Code: Order Number 74F2645SC Package Number M20B Package.

74F2645 Octal Bus Transceiver November 1989 Revised August 1999 74F2645 Octal Bus Transceiver with 25Ω Series Resistors in the Outputs General Description This device is an octal bus transceiver designed for asynchronous two-way data flow between the A and B busses and is functionally equivalent to the 74F645. The 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors. Both busses are capable of sinking 12 mA, sourcing 15 mA, have 3-STATE outputs, and a common output enable pin. The direction of data flow is determined by the transmit/receive (T/R) input. The 74F2645 is a low power version of the 74F245 with 25Ω series resistors in the outputs.
