- Bidirectional 8-bit bus transceiver with 3-state outputs for flexible bus direction control
- Adjustable output voltage allows direct level translation between 5V and low-voltage (2.7V–3.3V) logic systems
- Low-voltage CMOS (LVC) technology ensures low power consumption and high-speed operation
- Available in 24-pin Small Outline Package (SOIC/DW) for compact PCB designs
Applications
The SN74LVCC4245ADW is widely used in mixed-voltage digital systems for level translation between 5V legacy logic and 3.3V or 2.5V modern processors. It is ideal for microcontroller interfaces, memory bus buffering, and FPGA I/O expansion where bidirectional signal flow and voltage compatibility are critical. Industrial control systems, communication equipment, and embedded computing boards commonly rely on this device to bridge different logic families reliably.

Frequently Asked Questions
What voltage levels does the SN74LVCC4245ADW support on Port A and Port B?
The SN74LVCC4245ADW supports two separate power-supply rails: Port A operates at 4.5V to 5.5V, while Port B operates at 2.7V to 5.5V. This dual-rail design allows seamless level translation between 5V TTL/CMOS logic and lower-voltage systems such as 3.3V or 2.5V LVTTL/LVCMOS devices.
How does the bidirectional control work on the SN74LVCC4245ADW?
The device uses a common DIR (direction) control pin to set the data flow direction for all 8 bits simultaneously. When DIR is high, data flows from Port B to Port A; when DIR is low, data flows from Port A to Port B. The OE (output enable) pin activates or tri-states all outputs, allowing multiple transceivers to share the same bus without contention.
What is the load capacitance specification for the SN74LVCC4245ADW?
The SN74LVCC4245ADW is specified with a maximum load capacitance (CL) of 50 pF. This parameter is important when designing bus layouts, as higher capacitive loads can degrade signal integrity and increase propagation delay. PCB traces and connected device inputs should be kept well within this limit for reliable high-speed operation.
What package does the SN74LVCC4245ADW come in, and what does the 'DW' suffix mean?
The SN74LVCC4245ADW is housed in a 24-pin wide Small Outline IC (SOIC) package, where the 'DW' suffix specifically denotes the wide-body SOIC variant (JEDEC R-PDSO-G24). This package offers a good balance between compact PCB footprint and ease of hand or automated soldering, making it suitable for both prototype and production environments.
