Texas Instruments 74LVC1G3208DBVRE4

Overview

74LVC1G3208DBVRE4 from Texas Instruments is a single 3-input positive OR-AND gate logic IC performing Y = (A + B) ● C in 1.65-V to 5.5-V operation. It features 5 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for live insertion and partial-power-down applications. It is used in level-shifting interface logic within portable power management subsystems.

For engineers reviewing the 74LVC1G3208DBVRE4 datasheet, 74LVC1G3208DBVRE4 pinout, 74LVC1G3208DBVRE4 application, or 74LVC1G3208DBVRE4 equivalent, key selection criteria include its dual-function configurability (OR-AND / OR / AND), 3.3-V–optimized timing, NanoStar™ SOT-23-6 package footprint, and guaranteed Ioff behavior under back-drive conditions.

Technical Context

The 74LVC1G3208DBVRE4 implements a fixed Boolean function Y = (A + B) ● C using CMOS logic with input hysteresis (250 mV typ at 3.3 V) for noise immunity. Its Ioff circuitry actively disables outputs during power-down, preventing current backflow when VCC = 0 V.

It supports voltage translation: inputs tolerate up to 5.5 V independent of VCC, enabling interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. Output drive strength scales with VCC - delivering ±24 mA at 3.3 V and ±32 mA at 4.5 V - while maintaining VOL ≤ 0.55 V and VOH ≥ 2.3 V under full load.

FAQ

What logic function does the 74LVC1G3208DBVRE4 implement?

The 74LVC1G3208DBVRE4 implements the Boolean function Y = (A + B) ● C as a single 3-input positive OR-AND gate. When configured with C tied to VCC, it acts as a 2-input OR gate (Y = A + B); with A or B tied to GND, it functions as a 2-input AND gate (Y = B ● C or Y = A ● C). All configurations are supported per TI's Function Selection Table in SCES605B.

Does the 74LVC1G3208DBVRE4 support partial power-down operation?

Yes, the 74LVC1G3208DBVRE4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow through the device. This feature is fully characterized per JESD 78 Class II latch-up standards and supports live insertion, hot-swap, and partial-power-down mode in systems with mixed-rail power domains.

What is the maximum operating temperature range for the 74LVC1G3208DBVRE4?

The 74LVC1G3208DBVRE4 is rated for operation from –40°C to +125°C ambient temperature. This extended range is confirmed in the Recommended Operating Conditions table of SCES605B and applies to all electrical specifications including tpd, VOH/VOL, and Ioff, making it suitable for under-hood automotive and industrial control environments.

Can the 74LVC1G3208DBVRE4 interface between 1.8-V and 5-V logic domains?

Yes, the 74LVC1G3208DBVRE4 supports true voltage translation: inputs accept voltages up to 5.5 V regardless of VCC level, and outputs swing rail-to-rail (0 V to VCC). With VCC = 1.8 V, it can safely receive 5-V inputs and drive 1.8-V loads - eliminating external level shifters in mixed-voltage signal paths.

Is the 74LVC1G3208DBVRE4 pin-compatible with other SOT-23-6 logic gates?

No - the 74LVC1G3208DBVRE4 has a unique pinout (A-B-GND-C-Y-VCC) specific to its OR-AND function. It is not pin-compatible with standard 2-input OR, AND, or NAND gates in SOT-23-6 (e.g., SN74LVC1G08, SN74LVC1G32), as those assign different signals to pins 1, 2, 4, and 5. Layout reuse requires verification against the DBV mechanical drawing.
