onsemi NC7SV08L6X

Overview

NC7SV08L6X from onsemi is a single 2-input AND gate in MicroPak (UDFN6) package, designed for ultra-low-power logic in space-constrained applications operating from 0.9 V to 3.6 V supply. It delivers 1.6 ns typical propagation delay at 3.3 V, supports ±24 mA I_O drive, and features IOFF partial power-down protection. It is used in battery-powered IoT sensor interfaces requiring rail-to-rail input tolerance and low quiescent current.

For engineers reviewing the NC7SV08L6X datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (0.9–3.6 V), output drive strength (±24 mA at 3.3 V), input overvoltage tolerance (up to 3.6 V), IOFF functionality for partial power-down, and MicroPak UDFN6 footprint compatibility with high-density PCB layouts.

Technical Context

The NC7SV08L6X implements standard positive-logic AND function (Y = A · B) with CMOS-compatible inputs and push-pull outputs. Its IOFF circuitry disables both input and output paths when V_CC = 0 V, preventing back-drive current during partial power-down - critical for mixed-voltage system interconnects.

It operates across −40 °C to +85 °C with guaranteed performance at all V_CC levels from 0.9 V to 3.6 V. Input thresholds scale with V_CC (VIH = 0.65×V_CC, VIL = 0.35×V_CC), enabling interoperability across multiple supply domains without level shifters.

Key Specifications

FAQ

Is NC7SV08L6X still in production and supported for new designs?

No - according to onsemi's official datasheet (Rev. 5, June 2024), NC7SV08L6X is marked "DISCONTINUED" and "not recommended for new design." However, Aetrix Electronics maintains active inventory and offers lifecycle coordination support, including last-time-buy planning and cross-reference guidance for qualified replacements like NC7SZ08P5X or SN74LVC1G08DBVR. NC7SV08L6X remains fully functional and electrically identical to its active variants.

What is the correct pin 1 orientation for NC7SV08L6X in tape-and-reel delivery?

Per onsemi's ordering information, NC7SV08L6X uses Q4 orientation in tape-and-reel packaging: pin 1 is located at the top-left corner when the reel is viewed with the component tape facing upward and the leader end entering from the left. This matches JEDEC-standard UDFN6 orientation and is verified in Case 517DP mechanical drawings. Always confirm via optical inspection using the laser-marked dot adjacent to pin 1 on the package top surface.

Does NC7SV08L6X require external pull-up or pull-down resistors on its inputs or output?

No - NC7SV08L6X has no internal pull resistors and does not require external ones for standard AND operation. Its CMOS inputs have ≤0.5 µA leakage (I_IN) and are overvoltage-tolerant, so externally pulled inputs are only needed if a defined logic state is required during power-up/power-down sequences. The push-pull output (Pin 4) actively drives both HIGH and LOW states, eliminating need for external pull-ups in most gating applications.

Can NC7SV08L6X safely interface a 3.3 V microcontroller GPIO with a 1.2 V FPGA I/O bank?

Yes - NC7SV08L6X can operate from 1.2 V V_CC (within 0.9–3.6 V range) while accepting 3.3 V inputs due to its 3.6 V overvoltage-tolerant inputs. At V_CC = 1.2 V, VOH ≈ 1.1 V (min) and VOL ≈ 0.12 V (max), which meets 1.2 V FPGA input thresholds (VIH ≥ 0.65×V_CC, VIL ≤ 0.35×V_CC). Thus, NC7SV08L6X serves as a robust, single-chip level translator without external components.

How does the IOFF feature of NC7SV08L6X behave when V_CC is ramping or partially powered?

IOFF activates when V_CC falls below ~0.2 V and remains active until V_CC exceeds ~0.5 V. During this transition, both inputs (A, B) and output (Y) present high-impedance, leakage-limited paths (<0.5 µA). This prevents current backflow from powered downstream circuits into the unpowered NC7SV08L6X domain - a critical safeguard in hot-plug or multi-rail sequencing scenarios. The behavior is validated across −40 °C to +85 °C per datasheet Figure 3 test conditions.
