Product details
Overview
SN74LVC1G125YZPR from Texas Instruments is a single 3-state bus buffer gate in a 5-pin DSBGA (YZP) package, supporting 1.65–5.5V VCC operation, 3.7ns max propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled live insertion for high-density board-level signal routing in SSD and video infrastructure systems.
For engineers reviewing the SN74LVC1G125YZPR datasheet, SN74LVC1G125YZPR pinout, SN74LVC1G125YZPR application, or SN74LVC1G125YZPR equivalent, key selection criteria include its over-voltage tolerant inputs (up to 5.5V), ultra-small 1.39mm × 0.89mm footprint, 10μA max ICC, and guaranteed 3-state behavior during power sequencing - critical for shared-bus isolation in industrial embedded and broadcast equipment.
Technical Context
The SN74LVC1G125YZPR implements a noninverting CMOS buffer with active-low 3-state enable (OE), where Y = A when OE = L and Y = high-impedance when OE = H. Its balanced output stage supports symmetrical sourcing/sinking up to ±24mA at 3.3V while maintaining rail-to-rail VOH/VOL compliance across 1.65–5.5V supply range.
It features Ioff circuitry that disables all outputs at 0V VCC, enabling partial-power-down mode without back-drive risk, and includes over-voltage tolerant inputs that accept 0–5.5V signals regardless of VCC level - allowing seamless level translation between 3.3V logic domains and 5V peripherals without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across 1.8V, 2.5V, 3.3V, and 5V logic families |
| tpd (max) | 3.7ns at 3.3V, CL = 15pF - ensures sub-4ns timing margin for high-speed data acquisition interfaces |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple CMOS loads or moderate capacitive traces without buffering |
| Ioff Leakage | ±10μA at 5.5V - guarantees safe hot-plug operation and prevents back-driving in powered-down subsystems |
| Input Voltage Range | 0V to 5.5V - supports TTL-compatible and over-voltage tolerant input signaling independent of VCC |
| ICC (max) | 10μA - enables ultra-low static power in always-on monitoring circuits and battery-backed modules |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, military radar, and industrial motor control environments |
Pinout & Package
SN74LVC1G125YZPR uses a 5-ball DSBGA (YZP) package measuring 1.39mm × 0.89mm with bottom-side ball layout. The package supports solder reflow per JEDEC J-STD-020 and offers thermal resistance RθJA = 130°C/W - optimized for compact, thermally constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Noninverting input accepting 0–5.5V; drives Y when OE is asserted low |
| OE | Enable Control | Active-low 3-state enable; must be pulled high via resistor during power-up to ensure Hi-Z default state |
| Y | Buffered Output | True-output with CMOS-compatible VOH/VOL; high-impedance when OE = H |
| VCC | Power Supply | Primary supply rail (1.65–5.5V); powers internal logic and output stage |
| GND | Ground Reference | Return path for all currents; requires low-inductance connection to minimize switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant inputs | Accepts 0–5.5V signals regardless of VCC setting - eliminates need for external level shifters in mixed-supply systems |
| Ioff partial-power-down | Disables outputs at 0V VCC with <±10μA leakage - enables safe live insertion into powered-backplane systems |
| Ultra-small DSBGA footprint | 1.39mm × 0.89mm area - reduces PCB real estate by >60% vs. SOT-23, critical for SSD and portable video encoders |
| Balanced CMOS 3-state outputs | ±24mA drive symmetry at 3.3V - minimizes ground bounce and ensures clean bus release in shared-line applications |
| Low ICC quiescent current | ≤10μA across full temperature range - extends battery life in always-on sensor interface modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | SOT-23-5 package (2.9mm × 2.8mm); higher RθJA (357°C/W); same electrical specs | Less suitable for space-constrained SSD or portable video encoders due to 3.5× larger footprint | Preferred when manual assembly or legacy board compatibility outweighs miniaturization needs |
| NC7SZ125P5X | SC70-5 package; 3.5ns tpd at 3.3V; 1.65–5.5V VCC; ±24mA drive; no Ioff support | Lacks Ioff - unsuitable for live-insertion or partial-power-down systems requiring back-drive protection | Select only for cost-sensitive, fixed-power applications where hot-swap capability is not required |
Compared with SN74LVC1G125DBVR, SN74LVC1G125YZPR saves >60% board area and improves thermal performance by 70% (RθJA 130 vs. 357°C/W), while NC7SZ125P5X trades Ioff safety for marginally faster propagation but cannot replace SN74LVC1G125YZPR in powered-down subsystem isolation.

FAQ
What is the recommended pull-up resistor value for OE on SN74LVC1G125YZPR?
The OE pin of SN74LVC1G125YZPR should be tied to VCC through a pull-up resistor to ensure high-impedance state during power-up. TI recommends a 10kΩ resistor, sized to accommodate the device's maximum Ioff leakage (±10μA) and maintain OE < 0.3×VCC during assertion. This value balances fast enable timing, low static current, and noise immunity in high-density layouts.
Does SN74LVC1G125YZPR support 5V-tolerant inputs when VCC = 1.8V?
Yes, SN74LVC1G125YZPR supports 5V-tolerant inputs across its full VCC range (1.65–5.5V). When VCC = 1.8V, the A and OE inputs accept 0–5.5V signals without damage or functional degradation - enabling direct interfacing with 5V microcontrollers or legacy peripherals while operating from a 1.8V supply rail.
Can SN74LVC1G125YZPR drive a 50pF load while meeting tpd specifications?
Yes, SN74LVC1G125YZPR is characterized for CL = 15pF and CL = 30/50pF loads. At 3.3V VCC and –40°C to +125°C, its maximum tpd remains ≤4.7ns with 50pF loading - fully compliant with timing requirements for high-speed data acquisition and video infrastructure applications where trace capacitance exceeds typical board parasitics.
Is SN74LVC1G125YZPR qualified for automotive applications?
SN74LVC1G125YZPR is not AEC-Q200 qualified. It operates across –40°C to +125°C and meets JESD78 Class II latch-up immunity, making it suitable for industrial and military applications, but TI does not certify this specific YZP variant for automotive use. For automotive designs, consult TI's Automotive Qualified Logic portfolio for AEC-Q100-compliant alternatives.
How does Ioff functionality benefit system design with SN74LVC1G125YZPR?
Ioff in SN74LVC1G125YZPR disables all outputs when VCC = 0V, limiting leakage to ±10μA. This enables safe live insertion into powered-backplane systems, prevents back-driving of unpowered subsystems, and supports partial-power-down modes - critical for modular SSD controllers, field-upgradable video encoders, and redundant motor control architectures where subsystems power up/down independently.
