Key Features
- 16-bit bidirectional bus transceiver with 3-state outputs enabling half-duplex data transfer between two independent 16-bit buses
- Operates at both 2.5 V and 3.3 V supply voltages with ALVTH logic for high-speed mixed-voltage digital bus interfacing
- Dual output enable controls allow independent direction and tri-state management of each 8-bit half for flexible bus architecture
Applications
The SN74ALVTH16245DGG is used in high-speed digital systems to buffer and bidirectionally translate data across 16-bit buses operating at 2.5 V or 3.3 V, such as between FPGAs, ASICs, and memory modules. Its tri-state outputs allow multiple transceivers to share a common bus without contention, making it suitable for processor address and data bus expansion in embedded computing, industrial controllers, and communication backplane designs. The 48-pin SSOP package supports dense PCB layouts in compact multi-board systems.

Frequently Asked Questions
At what supply voltages can SN74ALVTH16245DGG operate and what bus width does it support?
The SN74ALVTH16245DGG is a 16-bit bus transceiver rated for operation at both 2.5 V and 3.3 V supply voltages, making it compatible with modern FPGA I/O banks and 3.3 V TTL logic families. The 16-bit width allows it to buffer an entire address or data bus in a single device, eliminating the need for two separate 8-bit transceivers in wide-bus applications.
How do the 3-state outputs of SN74ALVTH16245DGG prevent bus contention when multiple transceivers share a data bus?
The 3-state output architecture of SN74ALVTH16245DGG allows the 16 output drivers to be placed in a high-impedance state independently of logic levels, effectively disconnecting the device from the shared bus. Output enable pins control each 8-bit half independently, so arbitration logic can selectively activate only the required transceiver direction while keeping all others tri-stated, preventing simultaneous drive conflicts on 16-bit shared bus backplanes.
When should SN74ALVTH16245DGG be chosen over separate 8-bit bus buffers in a PCB design?
SN74ALVTH16245DGG is the preferred choice when the design requires a full 16-bit bidirectional bus in a single 48-pin SSOP device rather than two individual 8-bit transceivers such as 74ALVTH245, which each occupy a separate package. Using one 16-bit device reduces the component count by 1 IC, saves PCB area, lowers assembly cost, and simplifies routing by keeping all 16 data lines and both direction controls within a single 48-pin footprint.
