Frequently Asked Questions
How many data bits does SN74ABT16600DLRG4 support and what is its maximum output current?
The SN74ABT16600DLRG4 supports 18 bits of bidirectional data with a maximum output low current (I(ol)) of 64 mA. The device operates in the ABT logic family and is designed for high-drive, 3-state bus applications requiring robust signal drive across 18 channels simultaneously.
Which bus architectures benefit from using SN74ABT16600DLRG4 at 3.3 V instead of a narrower transceiver?
The 18-bit width of SN74ABT16600DLRG4 makes it ideal for memory bus interfaces that carry 16-bit data plus 2 parity bits, all in one device at 3.3 V supply. Its independent output enable for each direction, 50 pF rated load capacitance, and 3-state outputs let designers consolidate two 9-bit devices into a single 56-pin SOIC footprint, reducing BOM cost and PCB area in servers and embedded systems.
What package does SN74ABT16600DLRG4 use and how does it compare to standard 48-pin SOIC transceivers?
SN74ABT16600DLRG4 uses a 56-pin SOIC (JESD-30 code R-PDSO-G56), which is wider than common 48-pin packages but integrates 18 bidirectional channels plus control pins in one device. This avoids the need for multiple 8-bit or 9-bit transceivers, saving routing complexity when interfacing 18-bit buses such as ECC memory paths.
What clock enable and direction control features does SN74ABT16600DLRG4 provide for registered bus operation?
The device provides independent clock enable and an independent output enable for each transfer direction, giving designers fine-grained control over registered bus transactions. With a rated load capacitance of 50 pF per pin and bidirectional 18-bit data paths, it is suitable for synchronous bus architectures where direction must switch cleanly without glitches across all 18 channels.
