What are the key features of 74ALVTHR16245GR?
- 16-bit non-inverting bidirectional bus transceiver supporting LVTTL logic levels for high-density data-bus interfaces
- 2.5 V to 3.3 V operating range with ALVTHR process for compatibility with mixed-voltage 2.5 V and 3.3 V systems
- Bus-hold circuitry on all data inputs eliminates pull-up/pull-down resistors, reducing BOM and PCB area
- 48-pin TSSOP package with per-nibble direction and output-enable controls for maximum layout flexibility
What is 74ALVTHR16245GR used for?
The 74ALVTHR16245GR is well suited for high-speed data-bus buffering and level translation in servers, networking equipment, and FPGAs where 2.5 V and 3.3 V logic families must interoperate. Its dual-bus, 16-bit architecture supports memory bus expansion and backplane bus bridging in embedded systems. The low-voltage TSSOP footprint is also popular in handheld computing and industrial control cards that require compact, power-efficient logic glue.

Frequently Asked Questions
What supply voltage range and logic levels does the 74ALVTHR16245GR support for mixed-voltage designs?
The 74ALVTHR16245GR operates from a 2.5 V or 3.3 V supply and accepts LVTTL logic inputs, making it directly compatible with both 2.5 V and 3.3 V logic families. With V_IL up to 0.8 V and V_IH from 2.0 V, it reliably interfaces devices running at different voltage rails without external level-shift circuitry in many common design scenarios.
How does the bus-hold feature in 74ALVTHR16245GR reduce component count in a 16-bit parallel bus design?
The integrated bus-hold circuitry latches each of the 16 data lines to its last valid logic level when the bus is released, eliminating the need for 16 discrete pull-up or pull-down resistors. This reduces BOM count by up to 16 passive components and simplifies PCB routing, which is especially valuable on 48-pin TSSOP footprints where board space around the device is limited.
In which embedded or networking designs is 74ALVTHR16245GR a preferred choice over 74LVT16245 devices?
The ALVTHR variant is preferred when the system operates at 2.5 V rather than the typical 3.3 V of LVT devices, or when bus-hold inputs are required to prevent bus floating. Designs such as FPGA memory interfaces, PCI backplane bridges, and switch fabric cards at 2.5 V benefit from the 74ALVTHR16245GR's lower supply current consumption and guaranteed LVTTL thresholds at both 2.5 V and 3.3 V rails.
