description

These octal bus transceivers are designed for asynchronous two-waycommunication between data buses. The control-function implementationminimizes external timing requirements.

The devices allow data transmission from the A bus to the B bus orfrom the B bus to the A bus depending upon the logic level at thedirection-control (DIR) input. The output-enable () input can be used to disable thedevice so that the buses are effectively isolated.

The -1 version of the SN74ALS245A is identical to the standardversion, except that the recommended maximum I_OL isincreased to 48 mA. There is no -1 version of the SN54ALS245A.

The SN54ALS245A and SN54AS245 are characterized for operation overthe full military temperature range of -55°C to 125°C. TheSN74ALS245A and SN74AS245 are characterized for operation from0°C to 70°C.
