What are the key features of SN74CBT16210DGG?
- 10-bit 1:1 bus switch topology with active-low enable allows glitch-free bus isolation in address and data bus multiplexing designs
- TTL-compatible control inputs are directly driven by 3.3V or 5V logic without level-translation circuitry
- Near-zero propagation delay (sub-1 ns) through pass-gate FET switches preserves signal timing at bus speeds up to 500 MHz
- 50 pF load capacitance rating supports standard TTL bus loading without signal integrity degradation
- Lead-free 48-pin TSSOP with e4 JEDEC code meets RoHS and halogen-free requirements for consumer and industrial designs
What is SN74CBT16210DGG used for?
The SN74CBT16210DGG is used in memory bus isolation, processor-to-FPGA data path switching, and PCIe slot bus switches where 10 signals must be routed between two buses with near-zero latency. In server memory modules and DIMM interposers, it isolates DDR4 address lines during self-refresh cycles to reduce power consumption. The 48-pin TSSOP footprint integrates cleanly into existing bus driver PCB layouts replacing older 74CBTLV16210 footprints.

Frequently Asked Questions
How many bits does the SN74CBT16210DGG switch simultaneously, and what is its propagation delay?
The SN74CBT16210DGG switches 10 bits simultaneously in a 1:1 configuration controlled by a single active-low enable pin. As a pass-gate FET switch, it exhibits near-zero propagation delay, typically under 0.25 ns at 3.3V with 50 pF load, compared to 2-5 ns for registered bus drivers. This makes it suitable for high-speed data paths operating at 333 MHz DDR or faster.
Can the SN74CBT16210DGG operate in a 3.3V system interfacing with 5V legacy backplane signals?
Yes. The SN74CBT16210DGG supports bidirectional signal translation between 3.3V and 5V bus rails without additional components. The pass-gate architecture allows the higher of the two VCC potentials to pass through, clamped by the device's VCC supply. Control inputs are TTL-compatible from 2V logic high, so a 3.3V controller can enable or disable the switch while 5V signals propagate through the 10 bit-wide channel.
How does the active-low enable control of SN74CBT16210DGG simplify bus arbitration in a multi-master design?
By asserting the OE pin low for 10 passes simultaneously, a bus arbiter can connect or disconnect the full 10-bit data bus in a single GPIO toggle, achieving bus handover in less than 1 ns. Unlike registered switches that require clock edges, the SN74CBT16210DGG's combinatorial pass-gate responds immediately to the OE signal, making it ideal for zero-wait-state bus sharing between 2 processors accessing shared SRAM.
What are the package and lead-free compliance details of SN74CBT16210DGG for industrial procurement?
The SN74CBT16210DGG is housed in a 48-pin TSSOP (R-PDSO-G48) with 0.5 mm pitch and a package body of approximately 12.5mm x 6.1mm. It carries JESD-609 code e4, confirming lead-free and halogen-free construction that meets RoHS 3 Directive 2015/863/EU. The Pb-free solder finish supports peak reflow at 260°C, compatible with standard SAC305 assembly processes.
