SN74LS640DWR Description

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

***as Instruments: Octal bus transceivers 20-SOIC 0 to 70

***ark: IC, INVERTING BUS TRANSCEIVER, SOIC-20

***i-Key: IC TRANSCVR INVERT 5.25V 20SOIC

***XS: These octal bus transceivers are designed for asynchronous two-way communication between data buses. The 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 enable input (G) can be used to disable the device so the buses are effectively isolated.

***: The -1 versions of the SN74LS640 thru SN74LS642, SN74LS644, and SN74LS645 are identical to the standard versions except that the recommended maximum IOL is increased to 48 milliamperes. There are no -1 versions of the SN54LS640 thru SN54LS642, SN54LS644, and SN54LS645.

***AS INSTRUMENTS INC: The SN54LS640 thru SN54LS642, SN54LS644, and SN54LS645 are characterized for operation over the full military tempearture range of 55°C to 125°C. The SN74LS640 thru SN74LS642, SN74LS644, and SN74LS645 are characterized for operation from 0°C to 70°C.
