Product details
Overview
SN74LVC08ADBRE4 from Texas Instruments is a quadruple 2-input positive-AND gate IC designed for 1.65V to 3.6V operation, delivering 4.1ns max propagation delay at 3.3V, 5.5V-tolerant inputs, and ±24mA output drive at 3V. It performs Boolean Y = A • B logic across four independent gates and serves as a level translator in mixed-voltage 3.3V/5V digital systems such as server I/O expansion and LED display control.
For engineers reviewing the SN74LVC08ADBRE4 datasheet, SN74LVC08ADBRE4 pinout, SN74LVC08ADBRE4 application, or SN74LVC08ADBRE4 equivalent, key selection criteria include its wide VCC range (1.65–3.6V), 5.5V input tolerance, low propagation delay, latch-up immunity (>250mA), and SOIC-14 package compatibility with legacy board layouts.
Technical Context
The SN74LVC08ADBRE4 implements four independent 2-input AND functions using balanced CMOS push-pull outputs capable of sourcing and sinking up to ±24mA at 3V. Its standard CMOS inputs accept voltages up to 5.5V-enabling direct interfacing with 5V logic while operating from a 3.3V or lower supply.
It supports industrial and extended temperature ranges (–40°C to +125°C), features ESD protection exceeding 2000V HBM and 1000V CDM, and exhibits low ground bounce (<0.8V) and undershoot (>2V) at 3.3V, ensuring signal integrity in high-speed digital routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 3.6V - enables single-supply operation in battery-powered and low-voltage embedded systems. |
| Max tpd | 4.1ns at 3.3V - ensures sub-5ns timing for synchronous logic in high-throughput data paths. |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to 5V microcontrollers or sensors without external level shifters. |
| Output Drive | ±24mA at VCC = 3V - sufficient to directly drive LEDs, small-signal FETs, or multiple CMOS inputs. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and base station processor board use. |
| ESD Rating | 2000V HBM, 1000V CDM - meets JEDEC JESD22-A114 and JESD22-C101 for robust handling in manufacturing and field environments. |
| Latch-up Immunity | >250mA per JESD17 - prevents destructive latch-up during transient overvoltage events on I/O lines. |
Pinout & Package
SN74LVC08ADBRE4 uses the SOIC-14 (D) package: 8.65mm × 6.00mm body, 1.27mm lead pitch, surface-mount, plastic body with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B | Input | Eight dedicated logic inputs (two per gate); all tolerate 0–5.5V regardless of VCC. |
| 1Y, 2Y, 3Y, 4Y | Output | Four CMOS-compatible AND outputs; each drives ±24mA at 3V with rail-to-rail swing. |
| GND (Pin 7) | Ground Reference | Primary return path for all internal logic and output currents; must be low-impedance for noise control. |
| VCC (Pin 14) | Power Supply | Single positive supply input (1.65–3.6V); requires local 0.1µF bypass capacitor adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5.5V-tolerant inputs | Enables seamless 5V-to-3.3V logic translation without external components in mixed-supply systems. |
| Balanced push-pull outputs | Sources and sinks equal current (±24mA @ 3V), minimizing skew between rising/falling edges in timing-critical paths. |
| Low ground bounce & undershoot | Typical VOLP < 0.8V and VOHV > 2V at 3.3V - reduces switching noise coupling into analog sections or adjacent signals. |
| Wide temperature range | Specified from –40°C to +125°C - supports deployment in automotive engine control units and industrial motor drives. |
| High ESD/latch-up immunity | 2000V HBM, 1000V CDM, and >250mA latch-up rating - ensures reliability in automated assembly and harsh end-use environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08ADT | Same logic function and SOIC-14 package, but rated only for –40°C to +85°C (not +125°C). | Not suitable for under-hood automotive or high-ambient industrial deployments requiring extended temperature support. | Select SN74LVC08ADBRE4 when full –40°C to +125°C operation and TI's enhanced thermal derating (RθJA = 127.8°C/W) are required. |
| 74LVC08PW,118 | NXP variant in TSSOP-14 (5mm × 4.4mm); identical electrical specs but smaller footprint and different thermal resistance (RθJA = 150.8°C/W). | Preferred for space-constrained designs where board area is critical, but requires tighter thermal design margin. | Choose SN74LVC08ADBRE4 for legacy SOIC-14 compatibility, mechanical robustness, and higher thermal mass in high-reliability applications. |
Compared with SN74LVC08ADT and 74LVC08PW,118, SN74LVC08ADBRE4 offers guaranteed operation up to +125°C and superior thermal performance in SOIC packaging-making it optimal for mission-critical infrastructure where long-term reliability outweighs minor size advantages.

FAQ
What is the maximum supply voltage for SN74LVC08ADBRE4?
The absolute maximum supply voltage (VCC) for SN74LVC08ADBRE4 is 6.5V, but its recommended operating range is strictly 1.65V to 3.6V. Operating outside this range may cause parametric degradation or permanent damage. The device is not rated for continuous 5V VCC operation-only its inputs tolerate up to 5.5V. Always refer to Section 5.1 and 5.4 of the official TI datasheet SCAS283W for validated conditions.
Does SN74LVC08ADBRE4 support 5V logic level translation?
Yes, SN74LVC08ADBRE4 supports 5V-to-3.3V level translation via its 5.5V-tolerant inputs: inputs accept 0–5.5V regardless of VCC (1.65–3.6V), allowing direct connection to 5V microcontrollers or sensors. However, outputs swing only from GND to VCC (e.g., 0–3.3V), so it does not translate 3.3V-to-5V. For bidirectional translation, an external circuit or dedicated level shifter is required.
What is the thermal resistance (RθJA) of SN74LVC08ADBRE4?
SN74LVC08ADBRE4 in the SOIC-14 (D) package has a junction-to-ambient thermal resistance (RθJA) of 127.8°C/W, as specified in TI's July 2024 revision (SCAS283W). This value assumes standard JEDEC 2-layer board conditions. Derating begins above 70°C at 8 mW/°C. For thermal design, combine this with actual power dissipation (ICC × VCC + switching losses) to estimate junction temperature.
Can unused inputs on SN74LVC08ADBRE4 be left floating?
No-unused inputs on SN74LVC08ADBRE4 must be tied to either VCC or GND. Floating CMOS inputs cause undefined logic states, increased ICC, and potential oscillation or EMI. TI explicitly recommends connecting all unused inputs to a defined rail (Section 5.3/5.4 notes and Layout Guidelines in Section 8.3.1). For AND gates, tying unused inputs to VCC preserves logical identity; tying to GND forces output low.
Is SN74LVC08ADBRE4 RoHS-compliant and lead-free?
Yes, SN74LVC08ADBRE4 is RoHS-compliant and lead-free. Its orderable part number suffix "E4" denotes lead-free finish (NiPdAu), and TI's packaging documentation confirms compliance with EU RoHS Directive 2011/65/EU. The device uses matte tin (Sn) lead finish and carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH), supporting standard reflow profiles up to 260°C peak.
