What are the key features of 74ABT16600DGGRG4?
- 18-bit bidirectional registered transceiver with independent output enable per direction for flexible bus isolation and direction control
- Clock enable inputs on each port allow gated data latching, supporting synchronous bus multiplexing in high-speed backplane designs
- ABT family technology delivers 50 pF load drive with reduced ground bounce, ideal for 5 V bus interfaces at frequencies above 100 MHz
What is 74ABT16600DGGRG4 used for?
74ABT16600DGGRG4 is used in high-speed backplane bus interfaces, memory subsystem buffering, and multi-processor data bus applications requiring 18-bit bidirectional registered data transfer. The independent output enables and clock enable per direction make it suitable for arbitrated bus architectures where each side must be independently controlled. It finds application in ASIC prototyping boards and network switch line cards where large-bus isolation and registered data latching are needed.

Frequently Asked Questions
What bus width and direction control does 74ABT16600DGGRG4 provide?
The 74ABT16600DGGRG4 provides 18-bit bidirectional registered bus transceiver capability with independent output enable for each of the two directions. This allows either the A-to-B or B-to-A path to be independently enabled or tri-stated for 18 data lines simultaneously.
How does the clock enable feature of 74ABT16600DGGRG4 benefit synchronous bus design?
Each port direction of the 74ABT16600DGGRG4 has a dedicated clock enable pin, allowing data to be latched on selected clock edges without needing external gating logic. This reduces propagation delay uncertainty and prevents glitch capture in 5 V synchronous bus protocols operating above 50 MHz.
What package does 74ABT16600DGGRG4 use and how does it affect PCB routing density?
74ABT16600DGGRG4 comes in a 56-pin SSOP package with 0.635 mm pin pitch, offering a tighter footprint than a 56-pin SOIC. The SSOP's reduced 8 mm body width versus the SOIC's 14 mm width saves board area in dense bus buffer placement on server memory modules and backplane cards.
When is 74ABT16600DGGRG4 preferable to non-registered bus transceivers like 74ABT16245?
74ABT16600DGGRG4 is preferable when the design requires registered (latched) data synchronization between two bus segments, preventing metastability at clock domain crossings. Unlike the non-registered 74ABT16245 which passes data combinatorially, the 74ABT16600DGGRG4 adds setup-and-hold-based synchronization across its 18-bit data paths.
