Texas Instruments SN74LVC1G17YZPR

Overview

SN74LVC1G17YZPR from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V V_CC operation, performing Y = A logic with hysteresis (ΔV_T = 0.51–1.04V at 3V–5.5V), 4.6ns max t_pd at 3.3V/15pF, ±24mA output drive, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for consumer audio and display interfaces.

For engineers reviewing the SN74LVC1G17YZPR datasheet, SN74LVC1G17YZPR pinout, SN74LVC1G17YZPR application, or SN74LVC1G17YZPR equivalent, key selection criteria include Schmitt-trigger hysteresis width, I_off support for live insertion, ultra-small DSBGA-5 (1.75mm × 1.25mm) package compatibility, and 10μA max I_CC at 125°C.

Technical Context

The SN74LVC1G17YZPR implements a noninverting Schmitt-trigger buffer with separate positive-going (V_T+) and negative-going (V_T−) input thresholds - e.g., 1.48V/0.89V at V_CC = 3V - enabling robust noise rejection on slow or noisy signals. Its CMOS architecture supports voltage translation: inputs accept up to 5.5V regardless of V_CC (1.65–5.5V), while outputs swing rail-to-rail.

I_off circuitry actively disables outputs when V_CC = 0V, preventing back-drive current and supporting partial-power-down systems. The device meets JESD 78 Class II latch-up (>100mA) and exceeds JESD 22 ESD ratings: ±2000V HBM, ±1000V CDM.

FAQ

What is the function of SN74LVC1G17YZPR?

The SN74LVC1G17YZPR is a single noninverting Schmitt-trigger buffer that performs Y = A logic. Its hysteresis (e.g., 0.51V min at 3V V_CC) rejects noise on slow or noisy inputs, and its 5.5V-tolerant A input enables level translation. The SN74LVC1G17YZPR is commonly used for switch debouncing, clock conditioning, and interface isolation in portable electronics.

Does SN74LVC1G17YZPR support partial power-down?

Yes, SN74LVC1G17YZPR features I_off circuitry that disables outputs and limits leakage to <±10μA when V_CC = 0V. This prevents back-drive current from live I/O pins into an unpowered supply rail - a critical capability for hot-swap, multi-voltage domain, and battery-backed systems using the SN74LVC1G17YZPR.

What package type is SN74LVC1G17YZPR supplied in?

SN74LVC1G17YZPR is supplied in the YZP package: a 5-ball DSBGA (Die Size Ball Grid Array) with 1.75mm × 1.25mm body dimensions and 0.4mm ball pitch. Pinout is A–GND–DNU–V_CC–Y in a 3×2 array (ball B1 omitted). This ultra-compact package targets high-density portable designs where SOT-23 or SC-70 are too large.

What is the maximum operating temperature for SN74LVC1G17YZPR?

The SN74LVC1G17YZPR is rated for operation from –40°C to +125°C ambient temperature. Its electrical specifications - including propagation delay, output drive, and I_CC (≤10μA) - are guaranteed across this full industrial/automotive range, making the SN74LVC1G17YZPR suitable for under-hood, SSD, and set-top box applications with elevated thermal environments.

How does SN74LVC1G17YZPR differ from standard inverters or buffers?

Unlike standard buffers, SN74LVC1G17YZPR incorporates Schmitt-trigger inputs with defined hysteresis (V_T+ and V_T− thresholds), providing noise immunity on slow or noisy signals. It also offers 5.5V-tolerant inputs and I_off - features absent in basic LVC buffers like SN74LVC1G07. These capabilities make SN74LVC1G17YZPR uniquely suited for mechanical switch interfaces and multi-rail level translation.
