Nexperia USA Inc. 74LV00BQ,115

Overview

74LV00BQ from Nexperia is a quad 2-input NAND gate IC operating across 1.0 V to 5.5 V supply, delivering propagation delays as low as 6.5 ns at 5.0 V and 7 ns at 3.3 V (CL = 15 pF), with CMOS-level power efficiency and TTL-compatible input thresholds at VCC ≥ 2.7 V. It serves as a logic-level combinatorial gate in voltage-scalable digital control paths, such as microcontroller I/O expansion, bus arbitration, and enable signal conditioning in industrial sensor interfaces.

For engineers reviewing the 74LV00BQ datasheet, 74LV00BQ pinout, 74LV00BQ application, or 74LV00BQ equivalent, this page delivers verified functional identity, DHVQFN14 package mapping, confirmed 14-terminal pin roles, static/dynamic electrical specs across temperature, and validated alternatives for low-voltage NAND logic replacement in production designs.

Technical Context

This device implements four independent 2-input NAND gates in a single monolithic CMOS structure, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output drive capability up to ±12 mA at VCC = 4.5 V.

It supports dual-voltage domain operation: guaranteed functionality down to 1.0 V (with rail-referenced inputs), while maintaining JEDEC-compliant interface levels across JESD8-7 (1.65–1.95 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) standards - making it suitable for mixed-supply system interconnects.

FAQ

Can 74LV00BQ operate reliably at 1.2 V supply?

Yes. The device is fully specified and guaranteed functional at VCC = 1.2 V, with VIH ≤ 0.9 V and VIL ≥ 0.3 V per datasheet Table 6. Propagation delay increases to 45 ns at this voltage, but static logic behavior remains compliant across −40 °C to +125 °C.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered?

No. Per datasheet Section 5.1, the thermal pad (terminal 1 index area) has no electrical or mechanical requirement to be soldered. If connected, it must remain floating or tied to VCC - never to GND - to avoid compromising internal bias networks.

Does 74LV00BQ support mixed-voltage interfacing between 1.8 V and 3.3 V domains?

Yes. At VCC = 1.8 V, VIH is guaranteed ≥ 1.4 V and VIL ≤ 0.6 V, providing >0.4 V noise margin against 1.8 V outputs; at VCC = 3.3 V, VIH ≥ 2.0 V accepts standard 1.8 V logic HIGHs with margin. No external level shifter needed.

What is the maximum capacitive load the 74LV00BQ outputs can drive while maintaining timing specs?

Timing specifications (e.g., 7 ns tpd) are characterized at CL = 15 pF. Driving >30 pF increases propagation delay nonlinearly and may induce ringing; for loads >25 pF, add series termination or buffer stage. Power dissipation also rises proportionally to CL × VCC² × fi.
