What are the key features of SN74LVC3G34DCTR-P?
- Three independent non-inverting buffers in a single 8-pin SSOP provide signal fanout without additional components
- 1.65 V to 5.5 V wide supply voltage range allows direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains
- 32 mA output drive per channel enables the device to directly drive capacitive loads and short transmission lines
- High-speed LVC logic family with sub-10 ns propagation delay supports fast clock and data buffering up to 100 MHz
What is SN74LVC3G34DCTR-P used for?
The SN74LVC3G34DCTR-P is used to buffer and fanout clock signals, data lines, and reset signals in microcontroller and FPGA-based boards operating at mixed supply voltages. Its three separate buffer channels allow a single MCU output to drive multiple peripheral devices in parallel without loading the source. The compact SSOP-8 footprint makes it suitable for space-constrained boards where discrete discrete fanout buffers are required near high-speed signal paths.

Frequently Asked Questions
How many independent buffer channels does SN74LVC3G34DCTR-P contain and what logic function does each perform?
The SN74LVC3G34DCTR-P contains 3 independent non-inverting buffer channels in an 8-pin SSOP package. Each channel passes the input signal without inversion, with propagation delay under 10 ns at 3.3 V supply, making them suitable for clock fanout, reset distribution, and general signal buffering across 3 output loads simultaneously.
Which supply voltages does SN74LVC3G34DCTR-P support and can it translate between 3.3 V and 5 V logic?
The device operates from 1.65 V to 5.5 V VCC. When powered at 3.3 V, it accepts 5 V tolerant inputs, enabling it to buffer 5 V signals into 3.3 V outputs without external resistors or translation ICs. This makes it a simple one-chip solution for 5 V to 3.3 V level bridging in mixed-voltage board designs.
What output drive current does SN74LVC3G34DCTR-P provide and how many CMOS inputs can each channel drive?
Each buffer output can source or sink 32 mA at 3.3 V supply. A typical CMOS input draws under 10 µA, so one buffer channel can drive dozens of CMOS inputs or a single 50 Ohm transmission line segment. For capacitive loads up to 50 pF, all 3 channels can switch simultaneously without exceeding the device's power dissipation limit.
How does SN74LVC3G34DCTR-P compare to a single-gate buffer for clock distribution on a PCB with 3 receiver nodes?
A single-gate buffer forces the clock signal through a single output driving 3 parallel receiver inputs, increasing capacitive load and skew. Using SN74LVC3G34DCTR-P gives each receiver its own dedicated 32 mA buffer output, reducing inter-channel skew to under 1 ns and isolating load variations from the clock source, improving timing margin at frequencies above 50 MHz.
