Diodes Incorporated 74LV08AS14-13

Overview

74LV08AS14-13 from Diodes Incorporated is a quad 2-input AND gate IC in SO-14 package, operating from 2.0V to 5.5V supply, with 5.5V-tolerant inputs, IOFF-enabled partial power-down protection, and ±12mA output drive at 4.5V. It performs Boolean Y = A • B across four independent channels and is used for voltage-level translation and signal gating in mixed-voltage digital systems.

For engineers reviewing the 74LV08AS14-13 datasheet, 74LV08AS14-13 pinout, 74LV08AS14-13 application, or 74LV08AS14-13 equivalent, key selection criteria include input voltage tolerance (up to 5.5V), IOFF leakage (<5µA), propagation delay (as low as 4.1ns at 5V), output drive strength, and SO-14 thermal and layout compatibility.

Technical Context

The 74LV08AS14-13 implements four independent non-inverting AND logic functions with CMOS-compatible inputs and push-pull outputs. Its IOFF circuit disables outputs during power-down, preventing back-current flow when VCC = 0V while inputs remain biased up to 5.5V.

It supports wide-voltage operation (2.0–5.5V) with rail-to-rail input tolerance and guaranteed switching performance across –40°C to +125°C. Propagation delay varies from 4.1ns (5V, CL=15pF) to 17ns (2.5V, CL=15pF), and input capacitance is 3.3pF typical.

Key Specifications

Pinout & Package

FAQ

Can 74LV08AS14-13 operate reliably at 2.0V supply?

Yes. The device is fully specified down to 2.0V: VIH(min) = 1.5V, VOL(max) = 0.1V, and tPD(max) = 17ns at 2.5V (CL=15pF). At 2.0V, propagation delay increases slightly but remains functional within datasheet limits for low-speed control logic.

Does 74LV08AS14-13 require external pull-up resistors on unused inputs?

No. Unused inputs must be tied to either VCC or GND per datasheet Note 6 - floating inputs are prohibited due to increased ICC and potential oscillation. External pull-ups are unnecessary if hard-wired; internal structure does not provide weak pull-ups.

Is the SO-14 package of 74LV08AS14-13 compatible with standard reflow profiles?

Yes. The SO-14 package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports standard lead-free reflow profiles with peak temperatures up to 260°C. Thermal resistance (θJA) is 120°C/W, consistent with industry-standard SOIC footprints.

What is the maximum capacitive load this device can drive without signal degradation?

The datasheet specifies switching characteristics up to CL = 50 pF. Driving >50 pF increases tPD and may cause undershoot/overshoot; for loads beyond 50 pF, add series termination or buffer stages. Typical fan-out is 10 LVC/LV inputs (≈10 pF each) at 3.3V.
