Texas Instruments 74LVC1G3208DBVTG4

Overview

74LVC1G3208DBVTG4 from Texas Instruments is a single 3-input positive OR-AND gate (Y = (A + B) ● C) in a 6-pin SOT-23 (DBV) package, operating from 1.65 V to 5.5 V, with 5 ns max propagation delay at 3.3 V and ±24 mA output drive - used in logic-level translation and configurable gate functions within space-constrained industrial control and portable electronics.

For engineers reviewing the 74LVC1G3208DBVTG4 datasheet, 74LVC1G3208DBVTG4 pinout, 74LVC1G3208DBVTG4 application, or 74LVC1G3208DBVTG4 equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, input hysteresis (250 mV typ), 10 µA max ICC, and compatibility with 5.5 V-tolerant inputs across mixed-voltage systems.

Technical Context

The 74LVC1G3208DBVTG4 implements a fixed Boolean function Y = (A + B) ● C in positive logic, with configurable operation as a 2-input OR gate (C tied to VCC) or 2-input AND gate (A or B tied to GND). Its Ioff circuitry disables outputs during power-down to prevent backflow current, supporting live insertion and system-level power sequencing.

Input hysteresis (250 mV typ at 3.3 V) improves noise immunity for slow-rising signals, while voltage translation capability allows interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters - all within a 1.45 mm max height SOT-23 package.

FAQ

What logic function does the 74LVC1G3208DBVTG4 implement?

The 74LVC1G3208DBVTG4 implements the Boolean function Y = (A + B) ● C in positive logic. It can also be configured as a 2-input OR gate (by tying C to VCC) or a 2-input AND gate (by tying A or B to GND). All configurations retain the same 6-pin SOT-23 footprint and electrical behavior of the 74LVC1G3208DBVTG4.

Does the 74LVC1G3208DBVTG4 support partial power-down?

Yes, the 74LVC1G3208DBVTG4 features Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow from live inputs into a powered-down device. This makes the 74LVC1G3208DBVTG4 suitable for hot-swap, modular backplane, and multi-rail power sequencing applications.

Can the 74LVC1G3208DBVTG4 interface between 5 V and 3.3 V logic domains?

Yes, the 74LVC1G3208DBVTG4 accepts input voltages up to 5.5 V regardless of VCC (1.65–5.5 V), enabling direct connection to 5 V outputs while driving 3.3 V–compatible loads. This eliminates external level shifters in mixed-voltage systems using the 74LVC1G3208DBVTG4.

What is the maximum operating temperature range for the 74LVC1G3208DBVTG4?

The 74LVC1G3208DBVTG4 is rated for operation from –40°C to +125°C ambient temperature, meeting industrial-grade thermal requirements. This specification applies to all DBV-packaged variants including the 74LVC1G3208DBVTG4, as confirmed in TI's official SCES605B datasheet revision December 2013.

Is the 74LVC1G3208DBVTG4 pin-compatible with other SOT-23 logic gates?

The 74LVC1G3208DBVTG4 uses a standard 6-pin SOT-23 (DBV) footprint with pin 1 in quadrant Q3, matching TI's SN74LVC1Gxx family layout. However, pin functions differ across logic types - e.g., SN74LVC1G08DBVT assigns pins 1/2 to inputs and pin 4 to output, whereas the 74LVC1G3208DBVTG4 uses pins 1/2/5 as inputs and pin 4 as output. Always verify pin mapping before substitution.
