Product details
Overview
SN74LVC1G08MDCKREP from Texas Instruments is a single 2-input positive-AND gate logic IC in SC-70 (DCK) package, performing Y = A • B with 3.6 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for partial-power-down mode in extended temperature range –55°C to 125°C. It enables compact level-shifting and signal conditioning in space-constrained industrial control interfaces.
For engineers reviewing the SN74LVC1G08MDCKREP datasheet, SN74LVC1G08MDCKREP pinout, SN74LVC1G08MDCKREP application, or SN74LVC1G08MDCKREP equivalent, key selection criteria include its –55°C to 125°C operation, 5.5-V tolerant inputs, low ICC (10 µA max), Ioff-enabled backflow protection, and SC-70 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements standard positive-logic AND functionality using LVC CMOS technology, supporting mixed-voltage interfacing with input tolerance up to 5.5 V while operating from 1.65 V to 5.5 V supply. Its Ioff circuitry actively disables outputs during power-down, preventing current backflow into powered sections of the system.
The SN74LVC1G08MDCKREP delivers rail-to-rail output swing, specified timing performance across –55°C to 125°C, and robust ESD protection (2000-V HBM). It requires all unused inputs tied to VCC or GND per TI SCBA004 guidance to ensure deterministic operation and avoid floating-input-induced shoot-through or oscillation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08MDBVREP | SOT-23 (DBV) 5-pin package; 0.95-mm pin pitch; 2.9-mm length vs. DCK's 2.15-mm length | Requires PCB land pattern revision; slightly higher θJA (256°C/W vs. 252°C/W) | Select when legacy SOT-23 tooling or thermal margin above 252°C/W is preferred |
| SN74LVC1G08IDCKREP | Identical SC-70 (DCK) package but rated for –40°C to 85°C industrial temp range | Not qualified for extended temperature operation; lower cost for commercial-grade designs | Select when full –55°C to 125°C qualification is unnecessary and cost optimization is critical |
Compared with SN74LVC1G08MDBVREP, SN74LVC1G08MDCKREP offers 0.3-mm smaller footprint and 4°C/W better thermal resistance, while SN74LVC1G08IDCKREP shares identical packaging but sacrifices extended temperature capability for lower procurement cost in non-harsh environments.

FAQ
What is the maximum operating supply voltage for SN74LVC1G08MDCKREP?
The SN74LVC1G08MDCKREP supports a supply voltage range of 1.65 V to 5.5 V. Absolute maximum rating is 6.5 V, but sustained operation above 5.5 V violates recommended conditions and may compromise reliability or parametric performance. All electrical specifications-including propagation delay, output drive, and logic thresholds-are guaranteed only within the 1.65–5.5 V range per the SCES454C datasheet.
Does SN74LVC1G08MDCKREP support mixed-voltage interfacing?
Yes, SN74LVC1G08MDCKREP supports mixed-voltage interfacing via 5.5-V tolerant inputs. Inputs accept voltages from –0.5 V to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling direct connection to 5-V microcontrollers or FPGAs while powered from 1.8-V or 3.3-V rails-no external level shifters required for voltage translation.
How does the Ioff feature function in SN74LVC1G08MDCKREP?
The Ioff feature in SN74LVC1G08MDCKREP disables output drivers when VCC = 0 V, blocking current backflow from live inputs into a powered-down section. This prevents damage and unintended logic states in partial-power-down systems. The specification guarantees Ioff ≤ ±10 µA at VI or VO = 5.5 V and VCC = 0 V, meeting JEDEC JESD78 Class II latch-up immunity requirements.
What is the propagation delay of SN74LVC1G08MDCKREP at 1.8 V operation?
At VCC = 1.8 V ± 0.15 V, CL = 15 pF, and TA = –55°C to 125°C, the SN74LVC1G08MDCKREP has a maximum propagation delay (tpd) of 7.2 ns. This value is measured from input transition (10% to 90%) to output transition (10% to 90%), and remains within specification across the full extended temperature range-critical for timing-critical low-voltage sensor interfaces.
Is SN74LVC1G08MDCKREP RoHS compliant and lead-free?
Yes, SN74LVC1G08MDCKREP is RoHS compliant and features NiPdAu (NIPDAU) lead finish. Per TI's PACKAGE OPTION ADDENDUM, it carries "Yes" RoHS status and Level-1-260°C-UNLIM moisture sensitivity rating, making it compatible with standard Pb-free reflow profiles. The device meets JEDEC J-STD-020 and TI's General Quality Guidelines for green manufacturing.
