Overview
74F2243 Quad Bus Transceiver October 1988 Revised August 1999 74F2243 Quad Bus Transceiver with 25Ω Series Resistors in the Outputs General Description The 74F2243 is a quad bus transmitter/receiver which can be used for 4-line asynchronous 2-way data communications between data busses.
It is designed to drive the capacitive inputs of MOS memory drivers, address drivers, clock drivers, and bus-oriented transmitters/receivers.
The 25Ω series resistors in the outputs reduce ringing and eliminate the need for external resistors.
Features s 25Ω series resistors in outputs eliminate the need for external resistors s 2-Way asynchronous data bus communication s 3-STATE outputs s 12 mA source current s Designed to drive the capacitive inputs of MOS devices Ordering Code: Order Number 74F2243SC Package Number M14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.
150 Narrow Devices also available in Tape and Reel.
Specify by appending the suffix letter “X” to the ordering code.
