74ABT16245BDGG,518

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT16245BDGG,518 is a 16-bit bus transceiver with 3-state outputs manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports BiCMOS high-speed performance. The device features two output enables (1OE and 2OE) and two direction control inputs (1DIR and 2DIR), allowing configuration as one 16-bit or two 8-bit transceivers. It includes IOFF circuitry for partial power-down applications to prevent backflow current. The component is housed in a 48-lead TSSOP package (SOT362-1) and is specified for operation from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• BiCMOS technology provides high speed and strong output drive capability.
• IOFF circuitry prevents damaging backflow current during partial power-down states.
• Multiple VCC and GND pins are utilized to minimize switching noise and ground bounce.
• Live insertion and extraction operations are permitted without damage.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operation
• High-speed bidirectional bus interface
• Direct interface with TTL levels

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '518' against official Nexperia documentation to confirm exact packaging details and availability status. Ensure that the selected variant matches the required TSSOP48 package type and temperature range specifications for your design implementation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires high-speed transmission at 5V logic levels. The dual-direction control allows flexible routing between A and B buses. Consider the multiple ground and power pins for thermal management and signal integrity in dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT16245B family of 16-bit bus transceivers.
