What are the key features of 74LVCH16245ADGVRG4?
- 16-bit bidirectional non-inverting bus transceiver with direction control for flexible data path management
- LVC/LVTTL logic family supporting mixed 3.3 V and 5 V bus interfacing with bus-hold inputs
- Compact 48-pin TVSOP package enabling high channel density in space-constrained backplane designs
What is 74LVCH16245ADGVRG4 used for?
The 74LVCH16245ADGVRG4 is used in high-speed digital systems such as FPGA data bus buffering, memory interface expansion, and microprocessor peripheral isolation where 16-bit parallel data must be bridged bidirectionally between voltage domains. Its LVTTL compatibility makes it a practical buffer in 3.3 V backplane designs interfacing with legacy 5 V logic peripherals. The device is also deployed in industrial PLCs and network equipment front panels where high fan-out bus driving at low-voltage swing is required.

Frequently Asked Questions
How many data bits can 74LVCH16245ADGVRG4 transfer simultaneously and in which directions?
The 74LVCH16245ADGVRG4 transfers 16 bits simultaneously in either direction—A-to-B or B-to-A—controlled by a dedicated direction pin, making it a full 16-bit bidirectional bus transceiver for parallel data bus applications at LVTTL voltage levels.
What supply voltage and logic family does 74LVCH16245ADGVRG4 belong to?
It belongs to the LVC (Low-Voltage CMOS) family and operates from a 1.65 V to 3.6 V supply rail, while its inputs are 5 V-tolerant, allowing direct interfacing between 3.3 V host logic and 5 V legacy peripherals without additional level-shifting components.
In which package does 74LVCH16245ADGVRG4 come and how does that affect PCB routing?
The part comes in a 48-pin TVSOP package with 0.5 mm lead pitch and a body approximately 6.1 mm × 12.5 mm, providing 16 A-side and 16 B-side data pins plus controls in a slim outline that minimizes stub lengths on high-speed parallel bus traces.
When should 74LVCH16245ADGVRG4 be chosen over a unidirectional buffer like 74LVC16244A?
Choose 74LVCH16245ADGVRG4 whenever a bus must carry data in both directions—such as shared memory buses, I/O expansion ports, or processor data lines—because its bidirectional architecture with direction control replaces two unidirectional 16-bit buffers, saving board area and reducing part count by at least 1 IC.
