Nexperia USA Inc. 74LVT08D,118

Overview

74LVT08D,118 from Nexperia is a 3.3 V quad 2-input AND gate in SO14 package, featuring IOFF partial power-down protection, ±32 mA/±64 mA output drive, overvoltage-tolerant inputs up to 5.5 V, and operation from -40 °C to +85 °C. It serves as a level-shifting logic buffer in mixed-voltage digital systems such as industrial PLC I/O modules and FPGA peripheral interfacing.

For engineers reviewing the 74LVT08D,118 datasheet, 74LVT08D,118 pinout, 74LVT08D,118 application, or 74LVT08D,118 equivalent, key selection criteria include its BiCMOS output drive strength, 5.5 V input tolerance for TTL/3.3 V interface bridging, IOFF-enabled hot-swap capability, and SO14 thermal performance under sustained 32 mA sink loads.

Technical Context

This device implements four independent AND gates using BiCMOS technology to combine bipolar speed with CMOS low static power. Each gate accepts two inputs (nA/nB) and delivers a single active-high output (nY), with propagation delays as low as 3.0 ns at 3.3 V and 25 °C.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial system power-down-critical for hot-pluggable backplane designs. Input clamping diodes support 5.5 V tolerance while maintaining compatibility with 3.3 V supply rails.

FAQ

Does 74LVT08D,118 support true 5 V logic inputs?

Yes-it accepts input voltages up to 5.5 V regardless of VCC level, thanks to integrated input clamping diodes and overvoltage-tolerant design. This allows direct connection to legacy 5 V TTL buses while operating from a 3.3 V supply, eliminating external level shifters in most interface scenarios.

What happens to outputs during power-down?

When VCC drops to 0 V, the IOFF circuit automatically disables all four outputs, limiting output leakage to ±100 μA. This prevents damaging backflow current into powered sections of the system-a critical feature for hot-pluggable modules and partial-power-down architectures.

Can 74LVT08D,118 drive a 50 pF capacitive load at full speed?

Yes-its 3.0 ns tPLH and 3.4 ns tPHL are characterized with 50 pF load and 500 Ω termination per JEDEC test conditions. The BiCMOS output stage maintains this performance across -40 °C to +85 °C, making it suitable for driving PCB traces and multiple gate inputs within tight timing windows.

Is SO14 (SOT108-1) footprint compatible with TSSOP14 (SOT402-1)?

No-the SO14 package has 1.27 mm lead pitch and 3.9 mm body width, while TSSOP14 uses 0.65 mm pitch and 4.4 mm width. They require distinct PCB footprints and reflow profiles; board layout must match the specific variant ordered (e.g., 74LVT08D,118 vs. 74LVT08PW,118).
