Product details
Overview
SN74AUP1G34DRYR from Texas Instruments is a single non-inverting buffer gate in a 6-pin SON (DRY) package, operating across 0.8 V to 3.6 V supply range, delivering 4.1 ns max propagation delay at 3.3 V, 0.9 µA max ICC quiescent current, and 4.1 pF typical power dissipation capacitance - used for level translation and signal conditioning in ultra-low-power portable electronics.
For engineers reviewing the SN74AUP1G34DRYR datasheet, SN74AUP1G34DRYR pinout, SN74AUP1G34DRYR application, or SN74AUP1G34DRYR equivalent, key selection criteria include Ioff-enabled live insertion support, 3.6-V I/O tolerance with sub-1-µA static power, input hysteresis (250 mV typ), and ultra-small 1.45 mm × 1.00 mm footprint for space-constrained designs.
Technical Context
This device implements Y = A Boolean logic in positive logic using advanced CMOS AUP (Advanced Ultra-Low-Power) process technology. It supports mixed-voltage interfacing via 3.6-V tolerant I/Os while powered from as low as 0.8 V, enabling direct connection between 1.0–1.2 V microcontrollers and 3.3 V peripherals.
The integrated Ioff circuit disables outputs when VCC = 0 V, preventing back-drive current and supporting partial power-down systems. Input hysteresis improves noise immunity for slow-rising signals, and low dynamic power (Cpd = 4.1 pF typ at 3.3 V) minimizes switching energy in battery-powered applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables operation across modern low-voltage rails (e.g., 1.0 V uC core) and legacy 3.3 V I/O domains |
| tpd Max | 4.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering without violating setup/hold margins in high-speed interfaces |
| ICC Max | 0.9 µA at TA = –40°C to 85°C - delivers true ultra-low static power for always-on sensor nodes and wearables |
| Ioff Support | Yes - allows safe hot-plug insertion and prevents damaging back-current when VCC is unpowered |
| Input Hysteresis | 250 mV typ at 3.3 V - rejects noise on slow-switching inputs (e.g., mechanical switches, analog sensor outputs) |
| Cpd Typ | 4.1 pF at 3.3 V - reduces dynamic power consumption and EMI generation during high-frequency toggling |
| IOH/IOL | ±4 mA at 3.0 V - provides sufficient drive strength for fanout-1 loads while maintaining low edge rates for signal integrity |
Pinout & Package
SN74AUP1G34DRYR uses a 6-pin SON (Small Outline No-Lead) package with 1.45 mm × 1.00 mm body size and 0.5-mm pitch. The DRY package has exposed thermal pad and no leadframe; pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must remain floating or tied to GND/VCC per layout guidelines; no electrical function |
| 2 | Input A | CMOS-compatible input with 3.6-V tolerance and 1.5 pF typical input capacitance - accepts slow or noisy signals |
| 3 | GND | Ground reference for all internal circuitry - requires low-inductance connection to PCB ground plane |
| 4 | Output Y | Push-pull CMOS output with ±4 mA drive - supports point-to-point routing without termination |
| 5 | VCC | Power supply input - requires local 0.1 µF bypass capacitor placed adjacent to pin for stable low-noise operation |
| 6 | No Connect (NC) | Internally unconnected - same handling as Pin 1; no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | 0.9 µA max ICC enables multi-year battery life in always-on IoT endpoints and medical sensors |
| Wide VCC range | 0.8 V to 3.6 V operation supports direct interface between sub-1-V processors and 3.3-V peripherals without external level shifters |
| Ioff protection | Prevents back-drive current during partial power-down - critical for modular systems with hot-swap capability |
| Input hysteresis | 250 mV typical threshold margin eliminates chatter on slow or noisy inputs like pushbuttons or analog comparators |
| Low-noise output edges | Controlled slew rate limits overshoot/undershoot to <10% of VCC - preserves signal integrity on compact PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | Wider VCC range (1.65–5.5 V), higher ICC (10 µA typ), no Ioff, no input hysteresis | Better suited for 5-V legacy systems; lacks live-insertion and ultra-low-power features | Select when interfacing with 5-V logic or when higher drive strength (±24 mA) is required |
| 74AHC1G34GW,125 | Same 1.2–5.5 V VCC range, 2.5 ns tpd at 5 V, no Ioff, 3.5 pF Cpd, JEDEC-standard SC-70-5 | Optimized for speed over power; not suitable for sub-1-V operation or hot-swap scenarios | Choose for cost-sensitive industrial controls where 5-V compatibility and faster propagation are priorities |
Compared with SN74AUP1G34DRYR, SN74LVC1G34DBVR offers broader voltage compatibility but sacrifices ultra-low power and Ioff protection, while 74AHC1G34GW,125 delivers superior speed at 5 V but cannot operate below 1.2 V or support partial power-down - making SN74AUP1G34DRYR uniquely suited for next-generation battery-powered edge devices.

FAQ
What is the maximum operating temperature range for SN74AUP1G34DRYR?
SN74AUP1G34DRYR is rated for operation from –40°C to +85°C ambient temperature, meeting industrial-grade requirements. This range is validated across all electrical specifications including propagation delay, output drive, and quiescent current, ensuring reliability in medical, automotive-infotainment, and outdoor portable equipment environments where SN74AUP1G34DRYR is commonly deployed.
Does SN74AUP1G34DRYR support live insertion or hot-swap applications?
Yes, SN74AUP1G34DRYR includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging back-current flow during live insertion. This feature is explicitly tested and guaranteed per JESD78 Class II latch-up standards, making SN74AUP1G34DRYR suitable for modular systems such as ATCA carrier boards and field-replaceable sensor modules where SN74AUP1G34DRYR serves as an isolation buffer.
What is the input voltage tolerance of SN74AUP1G34DRYR when VCC = 1.2 V?
SN74AUP1G34DRYR supports 3.6-V tolerant inputs regardless of VCC level - so when VCC = 1.2 V, the A input can safely accept up to 3.6 V without damage or functional degradation. This enables direct connection to 3.3-V peripherals while powering SN74AUP1G34DRYR from a low-voltage rail, eliminating external level-shifters in mixed-voltage signal chains.
How does the input hysteresis of SN74AUP1G34DRYR improve noise immunity?
SN74AUP1G34DRYR provides 250 mV typical input hysteresis at 3.3 V, meaning the VIH and VIL thresholds differ by that amount - effectively creating a noise margin that prevents multiple transitions on slow-rising or electrically noisy signals. This behavior is confirmed in the datasheet's Feature Description and directly benefits SN74AUP1G34DRYR use in mechanical switch debouncing, sensor signal conditioning, and industrial control interfaces.
What is the recommended bypass capacitor for SN74AUP1G34DRYR?
Texas Instruments recommends a 0.1 µF ceramic capacitor placed as close as possible to the VCC pin of SN74AUP1G34DRYR, with low-inductance connection to the GND pin. This value is specified in Section 11 "Power Supply Recommendations" of the SCES603K datasheet and ensures stable operation across the full 0.8–3.6 V VCC range, especially critical for SN74AUP1G34DRYR's ultra-low-power performance and noise-sensitive applications.
