What are the key features of 74GTLPH1645DGGR?
- 16-bit non-inverting bidirectional bus transceiver bridging LVTTL and GTLP logic levels for mixed-voltage system buses
- Dual bus architecture with independent direction control for each 8-bit half, enabling flexible backplane and memory bus routing
- 56-pin TSSOP compact package minimizes board footprint in high-density server, workstation, and networking data-path designs
- GTLPH technology supports high-speed bus operation with reduced undershoot and improved signal integrity on 16-bit parallel buses
What is 74GTLPH1645DGGR used for?
The 74GTLPH1645DGGR is used in high-speed backplane bus interfaces, memory address/data buses, and processor-to-peripheral bridges where 16-bit bidirectional translation between LVTTL and GTLP logic domains is required. Networking line cards, server chipsets, and FPGA interface boards rely on its dual bus transceiver architecture to connect 3.3V LVTTL controllers with GTLP-terminated backplane traces. The 56-pin TSSOP package suits dense multi-layer PCB designs where parallel bus expansion with minimum area overhead is critical.

Frequently Asked Questions
What bus standards does the 74GTLPH1645DGGR translate between and how many bits does it handle simultaneously?
The 74GTLPH1645DGGR provides 16-bit non-inverting translation between LVTTL (3.3V) and GTLP logic levels in a single 56-pin TSSOP device, allowing simultaneous bidirectional transfer across two independent 8-bit buses with separate direction control pins.
For a server backplane design, how does the 74GTLPH1645DGGR reduce signal integrity problems on parallel buses?
GTLPH technology uses Gunning Transceiver Logic Plus with programmable bus-hold, reducing signal undershoot and termination noise on 16-bit parallel backplane traces, which extends reliable bus operation to higher frequencies and longer PCB trace lengths compared to plain LVTTL buffers.
How many direction control inputs does the 74GTLPH1645DGGR expose for flexible bus arbitration in multi-master systems?
The dual bus architecture provides independent direction control for each 8-bit port group, giving designers 2 direction pins that independently switch each half-bus between drive and receive modes, which suits split data/address bus topologies in memory controllers and FPGA interface cards using the 56-pin TSSOP package.
In which high-density PCB applications does the 56-pin TSSOP footprint of the 74GTLPH1645DGGR offer an advantage over DIP or QFP packages?
The 56-pin TSSOP occupies roughly 60% less board area than an equivalent QFP-64 at 0.65 mm pitch, making it practical for multi-layer server and networking PCBs where 16-bit bus width must be routed through tight spacing between processor and memory slots without consuming excessive routing channels.
