Texas Instruments SN74LVC2G80DCTRG4

Overview

SN74LVC2G80DCTRG4 from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in an 8-pin SSOP (DCT) package, supporting 1.65-V to 5.5-V V_CC operation, with 4.2 ns max propagation delay at 3.3 V, 160 MHz max clock frequency, and I_off support for live insertion. It serves as a compact, low-power storage element in high-speed digital interface buffering and data synchronization circuits.

For engineers reviewing the SN74LVC2G80DCTRG4 datasheet, SN74LVC2G80DCTRG4 pinout, SN74LVC2G80DCTRG4 application, or SN74LVC2G80DCTRG4 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed timing and voltage specifications, and real-world use context for signal integrity-critical edge-triggered storage in space-constrained designs.

Technical Context

This device implements two independent D-type flip-flops, each triggered on the rising edge of its dedicated clock input (1CLK, 2CLK), with non-inverting Q outputs and direct D inputs. Each channel operates synchronously without internal feedback or reset/set control, requiring external hold-time compliance (≥0.6 ns at 5.5 V) and setup-time adherence (≥0.9 ns at 5.5 V).

It features I_off circuitry that disables outputs during partial power-down, preventing back-drive current when V_CC = 0 V, and supports mixed-voltage interfacing via 5.5-V-tolerant inputs - critical for bridging 1.8-V logic domains to 3.3-V or 5-V systems without level shifters.

FAQ

What is the maximum clock frequency supported by SN74LVC2G80DCTRG4?

SN74LVC2G80DCTRG4 supports a maximum clock frequency of 160 MHz across its full operating voltage range (1.65 V to 5.5 V) and temperature range (–40°C to 125°C). This specification is guaranteed under load conditions of C_L = 15 pF and applies independently to both flip-flop channels. The device maintains this rate with t_pd ≤ 4.2 ns at 3.3 V, making SN74LVC2G80DCTRG4 suitable for high-speed data sampling and clock-domain crossing in modern digital systems.

Does SN74LVC2G80DCTRG4 support partial power-down operation?

Yes, SN74LVC2G80DCTRG4 includes integrated I_off circuitry that actively disables all outputs when V_CC is at 0 V, limiting I_off to ±10 μA maximum. This feature protects against damaging back-current flow during live insertion or partial system power-down - a key requirement in modular backplanes and hot-swappable modules. The I_off behavior is specified and tested per JEDEC JESD78 Class II latch-up standards, and SN74LVC2G80DCTRG4 maintains this protection across its full –40°C to 125°C operating range.

What package type and dimensions does SN74LVC2G80DCTRG4 use?

SN74LVC2G80DCTRG4 uses the SSOP (DCT) package: 8-pin, 3.95 mm × 4.9 mm body size, 1.3 mm maximum height, 0.65 mm lead pitch, and gull-wing leads. Pin 1 is located in quadrant Q3 per tape-and-reel orientation, with a beveled corner marking. Mechanical drawings confirm lead coplanarity ≤0.1 mm and seating plane tolerance per JEDEC MO-187 variation CA. This package is distinct from the DCU (VSSOP) and YZP (DSBGA) variants of the same base part number.

Can SN74LVC2G80DCTRG4 interface directly with 5-V logic inputs?

Yes, SN74LVC2G80DCTRG4 accepts input voltages up to 5.5 V regardless of V_CC level - meaning it can safely receive 5-V signals while powered from 1.8 V, 2.5 V, or 3.3 V. This 5.5-V-tolerant input capability is explicitly characterized in the datasheet and eliminates the need for external level-shifting components in mixed-voltage systems. However, output VOH/VOL levels remain constrained by the applied V_CC, so SN74LVC2G80DCTRG4 outputs cannot drive true 5-V logic thresholds unless V_CC = 5 V.

What is the typical power consumption of SN74LVC2G80DCTRG4 at 3.3 V?

At V_CC = 3.3 V and TA = 25°C, SN74LVC2G80DCTRG4 exhibits typical quiescent current (I_CC) of 5 μA and maximum of 10 μA. Dynamic power is governed by C_pd = 22 pF, resulting in ~0.7 mW dissipation at 10 MHz switching frequency. These values are measured with all inputs held static or toggling at 10 MHz under CL = 15 pF load. The low ICC and C_pd make SN74LVC2G80DCTRG4 especially suitable for always-on configuration registers and battery-operated edge nodes.
