Overview
The SN74LVC16245ADLRG4 is a 16-bit (dual-octal) noninverting bus transceiver produced by Texas Instruments. This device is designed for asynchronous communication between data buses and operates within a voltage range of 1.65 V to 3.6 V. It can be used as two 8-bit transceivers or one 16-bit transceiver, allowing 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 device supports mixed-mode signal operation, making it suitable for use in systems with both 3.3-V and 5-V components.
