Texas Instruments SN74LVC1G175YEPR

Overview

SN74LVC1G175YEPR from Texas Instruments is a single D-type flip-flop with asynchronous clear, designed for 1.65-V to 5.5-V operation, featuring 4.3 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for live insertion and partial-power-down modes. It serves as a compact edge-triggered storage element in space-constrained digital control paths such as serial data latching and clock-synchronized signal conditioning.

For engineers reviewing the SN74LVC1G175YEPR datasheet, SN74LVC1G175YEPR pinout, SN74LVC1G175YEPR application, or SN74LVC1G175YEPR equivalent, this page delivers verified functional behavior, NanoFree™ package mapping, timing constraints across –40°C to 125°C, and validated alternatives for low-voltage logic synchronization in portable and industrial systems.

Technical Context

The SN74LVC1G175YEPR implements positive-edge-triggered D-flip-flop logic with an active-low asynchronous clear (CLR), forcing Q low independent of CLK or D state. Its CMOS design supports voltage translation: inputs tolerate up to 5.5 V regardless of VCC, enabling interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V domains.

It integrates Ioff circuitry that disables outputs during power-down, preventing back-drive current flow, and meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM). The device operates reliably from –40°C to 125°C with tpd ≤ 6.7 ns at 3.3 V under worst-case conditions.

Key Specifications

Pinout & Package

SN74LVC1G175YEPR uses the NanoFree™ DSBGA (YZP) package - a 6-pin, 1.41 mm × 0.91 mm die-scale ball grid array where the silicon die itself forms the package body. This ultra-compact footprint minimizes PCB area and parasitic inductance, supporting high-density routing in portable and wearable electronics.

FAQ

What is the maximum clock frequency supported by SN74LVC1G175YEPR?

SN74LVC1G175YEPR supports up to 175 MHz at VCC = 5 V and TA = 25°C, with guaranteed minimum fclock of 100 MHz across –40°C to 125°C. At 3.3 V, the typical maximum frequency is 150 MHz, limited by tpd ≤ 4.6 ns and setup/hold timing margins. System-level performance depends on load capacitance and PCB trace impedance.

Does SN74LVC1G175YEPR require external pull-up or pull-down resistors on unused inputs?

Yes - all unused inputs of SN74LVC1G175YEPR must be tied to VCC or GND to prevent floating states that cause increased ICC, oscillation, or undefined output behavior. TI's application report SCBA004 explicitly mandates this for CMOS devices like SN74LVC1G175YEPR to ensure stable operation and avoid excessive power consumption.

Can SN74LVC1G175YEPR operate with VCC = 1.65 V while accepting 3.3-V input signals?

Yes - SN74LVC1G175YEPR supports down-translation: its inputs tolerate up to 5.5 V regardless of VCC level, so 3.3-V signals are fully compatible at VCC = 1.65 V. VIH and VIL thresholds scale with VCC (e.g., VIH ≥ 0.65×VCC), ensuring correct logic interpretation without external biasing.

What is the significance of the "YEPR" suffix in SN74LVC1G175YEPR?

The "YEPR" suffix identifies the specific package and reel format: Y = DSBGA (YZP), E = tape-and-reel packaging, P = 1.41 mm × 0.91 mm body size, R = 3000-unit large reel. This distinguishes it from DBV (SOT-23), DCK (SC70), or DRY (SON) variants, confirming its NanoFree™ die-scale construction and assembly compatibility.

How does the Ioff feature of SN74LVC1G175YEPR protect system-level circuits during power-down?

When VCC = 0 V, the Ioff circuitry in SN74LVC1G175YEPR disables all outputs, presenting high-impedance states that block current flow from powered I/O lines into the unpowered device. This prevents back-driving, latch-up, or damage to upstream drivers - a critical safeguard in hot-swap backplanes, battery-backed memory modules, and modular compute cards using SN74LVC1G175YEPR.
