SN74LVC2G74DCUR is a Texas Instruments single D-type flip-flop in VSSOP-8, large tape and reel — for data synchronization, clock division and signal conditioning in mixed-voltage logic designs. The LVC 1.65 V to 5.5 V range is the selection point: one tiny gate bridges low-voltage and 5 V domains. Selection advice: the DCUR suffix denotes VSSOP-8 in large tape and reel for production — the DCUT small-reel variant suits prototypes and low volumes. For dual flip-flops in one package, the 2G74 family saves board space. Match the order code to your assembly process. Parameters verified against the TI official product page.

SN74LVC2G74 is available in the following manufacturer order codes. They share the same SN74LVC2G74 design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| SN74LVC2G74DCTR | SSOP-8 | — | — |
| SN74LVC2G74DCUR | VSSOP-8 | LARGE T&R | Package/pins: VSSOP (DCU), 8 pins; SN74LVC2G74DCTR is SSOP (DCT), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinoutt. |
| SN74LVC2G74DCUT | VSSOP-8 | SMALL T&R | Package/pins: VSSOP (DCU), 8 pins; SN74LVC2G74DCTR is SSOP (DCT), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; SN74LVC2G74DCTR is LARGE T&R, 3,000 per pack. |
| SN74LVC2G74YZPR | DSBGA-8 | LARGE T&R | Package/pins: DSBGA (YZP), 8 pins; SN74LVC2G74DCTR is SSOP (DCT), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; rated operating temperature changes from -40 to 125 °C to -40 to 85 °C — verify the temperature grade. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — SN74LVC2G74DCTR (SSOP-8); SN74LVC2G74DCUT: Package/pins: VSSOP (DCU), 8 pins; SN74LVC2G74DCTR is SSOP (DCT), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; SN74LVC2G74DCTR is LARGE T&R, 3,000 per pack.; SN74LVC2G74YZPR: Package/pins: DSBGA (YZP), 8 pins; SN74LVC2G74DCTR is SSOP (DCT), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; rated operating temperature changes from -40 to 125 °C to -40 to 85 °C — verify the temperature grade.. SN74LVC2G74DCUR itself is the VSSOP-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
From the verified technical profile: Package code: VSSOP (DCU); Pin count: 8; Operating temperature: -40 to 125 °C. These are the catalog-recorded values for SN74LVC2G74DCUR — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
