74ABT16245CSSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16245CSSC is a 16-bit bidirectional bus transceiver with 3-state outputs housed in a 48-lead SSOP package. It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient temperature range of -40°C to +85°C. The device features byte-controlled logic allowing independent or combined operation, with separate OE and T/R inputs for each byte. It provides high output drive capabilities, sourcing up to 32 mA and sinking up to 64 mA. Propagation delays are specified at 3.9 ns maximum under standard conditions.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle data direction?

Data flow direction is determined by the T/R inputs. Each byte has a separate Transmit/Receive input that dictates whether data moves from Bus A to Bus B or vice versa.

What happens to the outputs during power-off?

The device maintains a high impedance state on both ports during the entire power-up and power-down cycle, preventing bus contention and allowing non-destructive hot insertion.
