Texas Instruments SN74LVC1G3208YEPR

Overview

SN74LVC1G3208YEPR from Texas Instruments is a single 3-input positive OR-AND gate performing Y = (A + B) ● C in 1.65-V to 5.5-V operation. It delivers 5 ns max propagation delay at 3.3 V, ±24-mA output drive, and supports down-translation to VCC. It enables configurable logic in space-constrained power management and interface signal conditioning circuits.

For engineers reviewing the SN74LVC1G3208YEPR datasheet, SN74LVC1G3208YEPR pinout, SN74LVC1G3208YEPR application, or SN74LVC1G3208YEPR equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, input hysteresis (250 mV typ @ 3.3 V), and NanoFree™ DSBGA package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC1G3208YEPR implements a fixed Boolean function Y = (A + B) ● C using CMOS logic with Schmitt-trigger input hysteresis for noise immunity. Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current flow when VCC = 0 V.

It operates across 1.65–5.5 V supply range with inputs tolerant to 5.5 V regardless of VCC level. The device supports three functional configurations: full 3-input OR-AND, 2-input OR (C tied to VCC), or 2-input AND (A or B tied to GND), all without external components.

FAQ

What logic function does the SN74LVC1G3208YEPR implement?

The SN74LVC1G3208YEPR implements the positive-logic Boolean function Y = (A + B) ● C. 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 operate within the 1.65–5.5 V VCC range, and the SN74LVC1G3208YEPR maintains consistent timing and drive strength across these modes without external components.

Does the SN74LVC1G3208YEPR support partial-power-down operation?

Yes, the SN74LVC1G3208YEPR includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow. This feature is fully specified per JESD 78 Class II latch-up standards and supports live insertion, hot-swap, and multi-rail power sequencing. The SN74LVC1G3208YEPR guarantees Ioff ≤ ±10 µA across –40°C to 125°C, enabling safe operation in systems with unpowered sections.

What is the maximum propagation delay of the SN74LVC1G3208YEPR?

The SN74LVC1G3208YEPR has a maximum propagation delay (tpd) of 5 ns at VCC = 3.3 V, CL = 15 pF, and TA = 25°C. At VCC = 5 V, tpd is 3.4 ns under the same conditions. Delay remains within specification across –40°C to 125°C operating temperature and up to 50 pF load capacitance, ensuring predictable timing in real-time control loops and high-speed data paths.

Can the SN74LVC1G3208YEPR accept 5-V inputs while operating at 1.8-V VCC?

Yes, the SN74LVC1G3208YEPR supports input voltages up to 5.5 V independent of VCC level - a feature called "down-translation." When VCC = 1.8 V, inputs A, B, and C may swing from 0 V to 5.5 V without damage or logic corruption. This allows direct interfacing with 5-V legacy peripherals or sensors while maintaining low-power 1.8-V core logic, eliminating external level shifters in the SN74LVC1G3208YEPR signal path.

What package type is used for the SN74LVC1G3208YEPR?

The SN74LVC1G3208YEPR uses the YZP package: a 6-ball DSBGA (Die Size Ball Grid Array) measuring 1.4 mm × 1.4 mm with 0.5 mm ball pitch and 0.5 mm max height. It employs Texas Instruments' NanoFree™ technology, where the silicon die serves as the package substrate. This construction minimizes parasitic inductance and enables routing under adjacent components - a critical advantage in compact wearable and IoT edge devices using the SN74LVC1G3208YEPR.
