Diodes Incorporated 74LV08AT14-13

Overview

74LV08AT14-13 from Diodes Incorporated is a quad 2-input AND gate IC in TSSOP-14 package, operating from 2.0V to 5.5V supply, with 5.5V-tolerant inputs, IOFF partial-power-down protection, and ±12mA output drive at 4.5V. It performs Boolean Y = A • B across four independent gates and is used for voltage-level translation and signal gating in mixed-voltage digital systems.

For engineers reviewing the 74LV08AT14-13 datasheet, 74LV08AT14-13 pinout, 74LV08AT14-13 application, or 74LV08AT14-13 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF-enabled power-down isolation, propagation delay (4.1–17 ns depending on VCC and load), and TSSOP-14 thermal and board-space advantages over SOIC.

Technical Context

This device implements four independent, non-inverting 2-input AND logic functions with CMOS-compatible push-pull outputs. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow, enabling safe hot-insertion and partial-power-down system architectures.

Input thresholds are VIL ≤ 0.3×VCC and VIH ≥ 0.7×VCC across 2.0–5.5V operation, supporting interoperability between 3.3V and 5V logic domains. Propagation delay varies from 4.1 ns (5.0V, CL=15pF) to 17 ns (2.5V, CL=15pF), with guaranteed performance over –40°C to +125°C ambient.

FAQ

Can 74LV08AT14-13 be used to interface 5V microcontrollers with 3.3V FPGAs?

Yes. Its 5.5V-tolerant inputs accept 5V logic-high signals while operating from a 3.3V supply, and its outputs swing rail-to-rail (0V to 3.3V), matching FPGA input thresholds. No external level-shifting components are needed for this direction of translation.

What happens to the outputs during power-down when VCC = 0V?

When VCC drops to 0V, the IOFF circuit activates and forces all four outputs into high-impedance state, blocking current flow from powered inputs or downstream circuits. Measured IOFF leakage is ≤5 μA, ensuring safe isolation without external pull resistors.

Is the TSSOP-14 package of 74LV08AT14-13 compatible with standard SO-14 footprints?

No. TSSOP-14 has 0.65mm lead pitch and 4.9mm × 4.5mm body, whereas SO-14 uses 1.27mm pitch and 8.7mm × 3.9mm body. They are mechanically and solder-reflow incompatible; separate PCB layout and stencil design are required for TSSOP-14.

Does 74LV08AT14-13 support Schmitt-trigger inputs for noisy environments?

No. The 74LV08A datasheet does not specify Schmitt-trigger input behavior; it uses standard CMOS input thresholds (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC). For hysteresis, external RC networks or dedicated Schmitt-trigger gates (e.g., 74LV14) must be used.
