SN74ALS640B-1DWR Description

***p One Stop Global: Bus XCVR Single 8-CH 3-ST 20-Pin SOIC T/R

***as Instruments: OCTAL BUS TRANSCEIVER 3-STATE 20-SOIC 0 to 70

***i-Key: IC TRANSCVR INVERT 5.5V 20SOIC

***as Instr.: These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable () input can be used to disable the device so that the buses are effectively isolated.

***NS: The -1 version of the SN74ALS640B is identical to the standard version, except that the recommended maximum IOL for the -1 version is increased to 48 mA. There is no -1 version of the SN54ALS640B.

***AS INST: The SN54ALS640B and SN54AS640 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS640B and SN74AS640 are characterized for operation from 0°C to 70°C.
