description
The ’LVT162245A devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for low-voltage
(3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. The devices allow data
transmission from the A bus to the B bus or from the B bus to the A bus, depending on 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 A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-
series resistors
to reduce overshoot and undershoot.
