Transceiver Logic IC; Logic Family:LS; Supply Voltage Min:4.75V; Supply Voltage Max:5.25V; Package/Case:20-SOP; No. of Pins:20; Operating Temperature Range:0°C to +70°C; Input Type:TTL; Leaded Process Compatible:Yes ;RoHS Compliant: Yes
***AS INSTRUMENT
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.
***AS
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.
***
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.
