SN74AHC16540DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHC16540DGGR is a 16-bit buffer and driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and utilizes the EPIC (Enhanced-Performance Implanted CMOS) process. The device features distributed VCC and GND pins to minimize high-speed switching noise and employs a flow-through architecture optimized for PCB layout. It provides two independent 8-bit buffers, each controlled by dual active-low output-enable inputs functioning as a 2-input AND gate. The component is housed in a 48-pin Thin Shrink Small-Outline (DGG/TSSOP) package.

Buffers, Drivers, Receivers, Transceivers Applications

• Wide data path bus interfaces
• High-performance digital buffering
• System-level I/O expansion

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGR' corresponds to the TSSOP-48 package and tape-and-reel quantity of 2000 units. Confirm that the RoHS status and lead finish (NIPDAU) match project requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target application before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide bus interface with 3-state capability is required. The AHC logic family offers improved speed and lower power consumption compared to older HC series devices. The flow-through pinout simplifies high-density PCB routing. Verify that the input voltage levels are compatible with the driving logic across the entire 2-V to 5.5-V supply range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Widebus Family of Texas Instruments logic products. It is designed specifically for applications requiring high-speed data transfer across wide buses. The SN74AHC16540 serves as a non-inverting buffer, distinct from transceivers or shift registers, providing direct signal amplification and isolation between different sections of a digital circuit.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AHC16540DL (SSOP package) if surface-mount form factor changes are acceptable. Verify compatibility with SN74AHCT16540 if TTL-compatible input thresholds are required instead of CMOS thresholds.
