SN74CBTLV3384DGVR

Overview

The SN74CBTLV3384DGVR is a low-voltage digital bus switch manufactured by Texas Instruments. It features two independent circuits, each configured as a 5-bit bidirectional bus switch with edge-triggered D-type flip-flops for data latching. The device operates on a single power supply ranging from 1.65 V to 3.6 V and is housed in a 24-pin TVSOP package. It supports TTL-compatible logic levels and includes three-state outputs to facilitate bus isolation.

Feature Summary

• Integrates edge-triggered D-type flip-flops to latch input data, ensuring stable switching states during bus transitions.
• Provides bidirectional data transfer capability between two buses with controlled three-state output buffering.
• Operates within a low voltage range of 1.65 V to 3.6 V, suitable for portable and battery-powered applications.

Applications

• Portable equipment requiring low-power signal routing
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing isolated bidirectional data paths

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-24 package and tape-and-reel shipping configuration. Confirm that the operating voltage range aligns with the system's 1.65 V to 3.6 V requirement. Ensure compatibility with TTL-compatible input logic levels before integration into the design.

Selection Notes

Select this component when designing systems that require low-voltage operation below standard 5 V logic levels. The inclusion of D-type flip-flops makes it appropriate for applications where data must be latched prior to switching to prevent glitches. Compare against non-latching variants if continuous transparency is preferred over stored state control.

Part Context

This part belongs to the SN74CBTLV3384 family of low-voltage bus switches. It shares functional similarities with other members like the SN74CBTLV3384DWR but differs in packaging and reel specifications. The device is designed to replace higher voltage counterparts in modern low-power digital designs.

FAQ

What is the function of the internal D-type flip-flops?

The D-type flip-flops latch the input data at the rising edge of the clock signal, allowing the switch to maintain a stable connection state even if the input signals change rapidly.

Is the device compatible with TTL logic levels?

Yes, the SN74CBTLV3384DGVR is specified as TTL-compatible, meaning it can interface directly with standard TTL logic outputs without additional level shifting.
