Texas Instruments SN74AUC2G80YEPR

Overview

SN74AUC2G80YEPR from Texas Instruments is a dual positive-edge-triggered D-type flip-flop in an 8-pin SSOP (DCT) package, operating from 0.8 V to 2.7 V with 1.9 ns max propagation delay at 1.8 V, ±8-mA output drive, and Ioff support for partial-power-down mode - used in low-voltage clock-domain synchronization and data latching in portable logic interfaces.

For engineers reviewing the SN74AUC2G80YEPR datasheet, SN74AUC2G80YEPR pinout, SN74AUC2G80YEPR application, or SN74AUC2G80YEPR equivalent, key selection criteria include sub-1.8-V timing performance, nanosecond-level tpd at 1.8 V, Ioff-enabled power sequencing, and compatibility with mixed-mode 1.8-V/3.3-V signal domains.

Technical Context

This device implements two independent edge-triggered D-flip-flops sharing no internal logic; each responds solely to its dedicated CLK input on the rising edge, with setup time as low as 0.5 ns and hold time as low as 0.1 ns at 1.8 V. It uses standard CMOS transmission-gate-based latch architecture with Schmitt-trigger-free inputs.

Designed explicitly for 1.65–1.95 V operation, it achieves 275 MHz maximum clock frequency at 2.5 V and maintains functional operation down to 0.8 V supply, while supporting 3.6-V I/O tolerance for mixed-voltage interfacing without level shifters.

FAQ

What is the minimum supply voltage at which SN74AUC2G80YEPR remains fully functional?

SN74AUC2G80YEPR operates fully across 0.8 V to 2.7 V, with guaranteed timing and logic functionality down to 0.8 V. At this minimum VCC, tpd increases to 5 ns and fmax drops to 50 MHz, but all DC parameters including Ioff and input thresholds remain valid per datasheet Section 6.3.

Does SN74AUC2G80YEPR support true bidirectional data flow between clock domains?

No - SN74AUC2G80YEPR is a unidirectional D-type flip-flop with separate D and Q terminals per channel. It does not implement bus transceivers or direction control. For bidirectional domain crossing, two SN74AUC2G80YEPR devices must be used in complementary configuration with external control logic.

Can SN74AUC2G80YEPR be used without external decoupling capacitors?

No - TI's datasheet mandates local 100-nF ceramic decoupling between VCC and GND pins, placed within 3 mm of the package. Omitting this causes timing violations and increased jitter due to supply noise coupling into the sensitive clock and data paths of SN74AUC2G80YEPR.

Is SN74AUC2G80YEPR pin-compatible with SN74AUC2G74YEPR?

No - SN74AUC2G74YEPR is a dual D-type latch (transparent) with different pinout: it places 1CLR and 1PRE on pins 1 and 2, whereas SN74AUC2G80YEPR assigns 1CLK and 1D to those positions. Their logic functions, timing behavior, and pin assignments are incompatible.

What is the meaning of "NanoFree™" in relation to SN74AUC2G80YEPR packaging?

NanoFree™ refers to TI's wafer-level chip-scale packaging (WLCSP) technology - but SN74AUC2G80YEPR uses SSOP (DCT), not NanoFree. The YEPR suffix denotes SSOP packaging; NanoFree variants carry YZP or DCU markings. This distinction is confirmed in TI's ordering table and package drawings.
