Key Features
- 16-bit registered bus transceiver with independent output enables for each direction enables full bidirectional registered data transfer control
- Clock enable input allows selective data latching on each cycle, reducing unnecessary switching activity in wide data bus systems
- ABT logic family provides 64mA output sink current at 50pF load for driving high-fanout 16-bit data buses reliably
- 3-state outputs with independent direction control allow multiple transceivers to share bidirectional buses without contention
Applications
The SN74ABT16952DLRG4 is used in wide data bus interfaces between processors, memory, and I/O subsystems in high-performance embedded computing, telecommunications, and industrial computing platforms. Its registered transceiver architecture with clock enable supports synchronous bidirectional data transfer, making it ideal for backplane bus drivers, memory bank interfaces, and FPGA I/O expansion in data-intensive designs. The independent direction enables and 16-bit width also suit VME, PCI, and custom bus backplane designs requiring high drive strength and registered timing.

Frequently Asked Questions
What does registered bus transceiver mean for the SN74ABT16952DLRG4?
A registered bus transceiver includes internal flip-flops (registers) that latch data on a clock edge before driving the output bus. The SN74ABT16952DLRG4 uses this registered architecture to provide synchronous, glitch-free bidirectional data transfer between two bus segments with independent direction control.
What is the bus width and direction capability of the SN74ABT16952DLRG4?
The SN74ABT16952DLRG4 handles 16-bit wide bidirectional data transfer with independent output enable control for each direction (A-to-B and B-to-A), making it suitable for full 16-bit or two independent 8-bit bus interface applications requiring registered buffering.
What is the logic family and output drive strength of the SN74ABT16952DLRG4?
The SN74ABT16952DLRG4 belongs to the ABT (Advanced BiCMOS Technology) logic family and provides 64mA maximum output sink current (IOL) with a 50pF rated load capacitance, enabling it to drive large capacitive bus loads and high-fanout connections in industrial systems.
What package does the SN74ABT16952DLRG4 use?
The SN74ABT16952DLRG4 is housed in a 56-pin SOP (Small Outline Package), a surface-mount package that accommodates the 16-bit wide bus width plus control signals while remaining compatible with standard SMT pick-and-place assembly equipment.
Is the SN74ABT16952DLRG4 RoHS compliant?
Yes, the SN74ABT16952DLRG4 is RoHS compliant and lead-free (JESD-609 Code: e4), meeting current international environmental regulations for hazardous substance restrictions in electronic components used in commercial and industrial products.
