description

These octal bus transceivers are designed for

asynchronous two-way communication between

data buses. The control-function implementation

minimizes external timing requirements.

GND

The devices allow data transmission from the

A bus to the B bus or from the B bus to the A bus

depending upon the logic level at the

direction-control (DIR) input. The output-enable

(OE) input can be used to disable the device so

that the buses are effectively isolated.

The -1 version of the SN74ALS245A is identical to

the standard version, except that the

20 19

recommended maximum I

is increased to

48 mA. There is no -1 version of the

SN54ALS245A.

The SN54ALS245A and SN54AS245 are

characterized for operation over the full military

temperature range of –55°C to 125°C. The

SN74ALS245A

and

SN74AS245

are

characterized for operation from 0°C to 70°C.
