Product details
Overview
SN74LVC1G17YZAR from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V operation, performing Y = A logic with hysteresis (ΔVT = 0.51–1.04 V), 4.6 ns max propagation delay at 3.3V, ±24 mA output drive, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for consumer audio/video interfaces.
For engineers reviewing the SN74LVC1G17YZAR datasheet, SN74LVC1G17YZAR pinout, SN74LVC1G17YZAR application, or SN74LVC1G17YZAR equivalent, key selection criteria include Schmitt-trigger hysteresis width, Ioff-enabled partial-power-down capability, ultra-small X2SON (DPW) 0.8 mm × 0.8 mm package compatibility, and 5.5V input tolerance enabling level translation in mixed-voltage systems.
Technical Context
The SN74LVC1G17YZAR implements a noninverting Schmitt-trigger buffer with distinct positive-going (VT+ = 1.48–3.33 V) and negative-going (VT– = 0.89–2.4 V) input thresholds across its 1.65–5.5 V supply range. Its CMOS architecture delivers rail-to-rail output swing and supports live insertion via Ioff circuitry that disables outputs when VCC = 0 V.
This device operates over –40°C to 125°C and maintains stable switching performance (tpd ≤ 6.5 ns at 3.3V, CL = 30 pF) while consuming ≤10 μA ICC in static mode. The DPW package features 0.5 mm pitch and 0.64 mm² footprint, optimized for space-constrained portable electronics requiring robust noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Input Voltage Tolerance | Up to 5.5 V - allows safe interfacing with higher-voltage signals without external level-shifting |
| Propagation Delay (tpd) | 4.6 ns max at 3.3 V, CL = 15 pF - supports clean signal routing up to ~100 MHz in low-capacitance paths |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive multiple LVC loads or moderate PCB traces without buffering |
| Hysteresis (ΔVT) | 0.51 V min at 3 V, 1.04 V max at 5.5 V - rejects noise on slow or noisy input edges (e.g., mechanical switches, analog sensor outputs) |
| Ioff Current | ±10 μA max - prevents back-drive current during power sequencing or hot-swap events |
| ESD Rating | ±2000 V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74LVC1G17YZAR is packaged in a 4-pin X2SON (DPW) variant with 0.5 mm pitch and 0.8 mm × 0.8 mm body size. Pin 1 = A (input), Pin 2 = GND, Pin 3 = Y (output), Pin 4 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | 5.5 V-tolerant Schmitt-trigger input; accepts slow/noisy signals and provides hysteresis-based noise rejection |
| GND | Ground reference | Return path for all internal logic and output current; must be low-impedance for stable threshold behavior |
| Y | Output | CMOS push-pull output with ±24 mA drive; rail-to-rail swing referenced to VCC and GND |
| VCC | Power supply | Single supply input (1.65–5.5 V); powers internal logic and output stage; requires local 0.1 µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the function of SN74LVC1G17YZAR?
The SN74LVC1G17YZAR is a single noninverting Schmitt-trigger buffer that performs Y = A logic with built-in hysteresis. It conditions slow or noisy digital signals by rejecting noise below its threshold window (ΔVT), ensuring clean, jitter-free output transitions - critical for reliable switch debouncing and analog-to-digital signal cleanup in the SN74LVC1G17YZAR's target applications.
Does SN74LVC1G17YZAR support 5 V logic levels?
Yes, SN74LVC1G17YZAR supports 5.5 V-tolerant inputs while operating from VCC as low as 1.65 V. This allows direct connection to 5 V sources (e.g., legacy microcontrollers or sensors) without external level-shifting components, with output swing referenced strictly to the applied VCC - making SN74LVC1G17YZAR ideal for mixed-voltage system interfacing.
What package type is used for SN74LVC1G17YZAR?
SN74LVC1G17YZAR uses the 4-pin X2SON (DPW) package: 0.8 mm × 0.8 mm body size, 0.5 mm pitch, and ultra-low profile. This package delivers the smallest footprint (0.64 mm²) in the SN74LVC1G17 family, optimized for space-constrained portable electronics where PCB real estate is at a premium.
How does the Ioff feature work in SN74LVC1G17YZAR?
The Ioff feature in SN74LVC1G17YZAR disables output drivers when VCC = 0 V, limiting Ioff current to ±10 μA max. This prevents damaging back-current flow from live inputs or outputs into a powered-down system - essential for hot-swap compliance and safe power sequencing in SSDs and modular audio docks using SN74LVC1G17YZAR.
What is the maximum operating temperature for SN74LVC1G17YZAR?
SN74LVC1G17YZAR is rated for continuous operation from –40°C to +125°C ambient temperature. This extended range supports deployment in thermally demanding environments such as automotive infotainment systems, industrial SSD controllers, and enclosed home theater equipment - all while maintaining full specification compliance for SN74LVC1G17YZAR's timing, drive, and hysteresis parameters.
