• IOFF circuitry for partial power-down mode operation
• BiCMOS high speed and output drive capability
• Latch-up performance exceeds 500 mA

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed bidirectional bus interfaces
• Partial power-down system architectures
• Mixed signal environments requiring TTL level interfacing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the selected part number corresponds to the non-bus hold version as indicated by the base model designation. Ensure design compliance with the specified absolute maximum ratings to prevent device damage during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit data transfer with integrated impedance matching. The absence of bus-hold inputs distinguishes this variant from the ABTH version. Consider the 4.5 V to 5.5 V operating range and BiCMOS speed characteristics for high-performance logic applications.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT family of high-speed BiCMOS logic devices. It provides a standard multibyte flow-through pin-out architecture suitable for replacing older 74FCT or 74ACT equivalents in high-speed digital designs. The TSSOP48 package offers a compact solution for dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABTH162245ADGG is a functional alternative but includes bus-hold data inputs. Verify if the bus-hold feature is compatible with the target application requirements before substitution.
