Texas Instruments SN74LVC1G80YZPR

Overview

SN74LVC1G80YZPR from Texas Instruments is a single positive-edge-triggered D-type flip-flop in a 5-pin DSBGA package, operating from 1.65V to 5.5V V_CC, with 4.2ns max propagation delay at 3.3V and ±24mA output drive. It implements synchronous data latching in clock-domain crossing, level-shifting, and frequency-division circuits for low-power portable electronics.

For engineers reviewing the SN74LVC1G80YZPR datasheet, SN74LVC1G80YZPR pinout, SN74LVC1G80YZPR application, or SN74LVC1G80YZPR equivalent, this page delivers verified electrical specs, NanoFree™ package thermal behavior, Ioff-enabled partial-power-down operation, and real-world timing constraints across –40°C to +85°C.

Technical Context

The SN74LVC1G80YZPR uses standard CMOS inputs with over-voltage tolerance up to 5.5V independent of V_CC, enabling mixed-voltage interfacing. Its edge-triggered logic transfers D-input data to Q-output on the rising clock edge when setup (1.3ns min at 3.3V) and hold (0.9ns min) timing requirements are met.

It features balanced push-pull outputs capable of sourcing/sinking ±24mA at 3.3V, with Ioff circuitry that disables outputs during power-down to prevent back-drive current. The device lacks asynchronous preset/clear, so initial Q-state is undefined without external initialization.

Key Specifications

Pinout & Package

FAQ

What is the maximum clock frequency supported by SN74LVC1G80YZPR?

The SN74LVC1G80YZPR supports up to 160MHz clock frequency at V_CC = 1.8V, 2.5V, 3.3V, or 5.5V across its full operating temperature range (–40°C to +85°C), confirmed by timing characterization with CL = 15pF. At 3.3V, the 4.2ns max t_pd enables reliable operation well above 100MHz in typical PCB layouts.

Does SN74LVC1G80YZPR support partial power-down mode?

Yes, SN74LVC1G80YZPR fully supports partial power-down via its I_off feature: when V_CC = 0V, all I/O pins enter high-impedance state with leakage limited to ±10µA, preventing back-drive current into powered-down sections - critical for hot-swap and multi-rail architectures.

Can SN74LVC1G80YZPR interface with 5V logic while powered at 3.3V?

Yes, SN74LVC1G80YZPR accepts input voltages up to 5.5V on D and CLK pins regardless of V_CC level - enabling direct connection to 5V sources while operating at 3.3V, without external level shifters or clamping diodes.

What is the thermal resistance (R_θJA) of SN74LVC1G80YZPR?

The SN74LVC1G80YZPR has a junction-to-ambient thermal resistance of 136.9°C/W in its DSBGA package, significantly lower than SOT-23 (357.1°C/W) or SC70 (371°C/W) variants - enabling higher sustained power dissipation in compact layouts without forced airflow.

Is there an initial state guarantee for the Q output of SN74LVC1G80YZPR?

No, SN74LVC1G80YZPR has no asynchronous preset or clear; the initial Q state after power-up is undefined. System-level initialization - such as driving D HIGH via microcontroller GPIO before first CLK edge - is required to establish known output polarity.
