onsemi NLV14077BDR2G

Overview

NLV14077BDR2G from onsemi is a quad exclusive NOR (XNOR) gate IC in SOIC-14 package, operating across 3.0–18 VDC supply, delivering VOH ≥ 4.95 V at VDD = 5 V and VOL ≤ 0.05 V, with propagation delay of 175 ns (max) at 5 V/50 pF, used in automotive logic-level signal conditioning and noise-immune digital control circuits.

For engineers reviewing the NLV14077BDR2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, rail-to-rail input voltage tolerance (−0.5 to VDD + 0.5 V), guaranteed output drive (±4.2 mA at VDD = 15 V), and compatibility with legacy CD4077B-based designs requiring low-quiescent-current CMOS logic.

Technical Context

The NLV14077BDR2G implements four independent CMOS XNOR gates using complementary P- and N-channel enhancement-mode MOSFETs on a single monolithic die, supporting true dual-supply operation with inputs and outputs referenced strictly to VSS and VDD. Its architecture ensures high noise immunity via double-diode input protection and buffered outputs capable of driving two low-power TTL loads over −55 °C to +125 °C.

Each gate features symmetrical input thresholds-VIH = 3.5 V (min) and VIL = 1.5 V (max) at VDD = 5 V-with propagation delays scaling linearly with load capacitance (tPLH/tPHL = 0.90 ns/pF × CL + 130 ns typical at 25 °C). Unused inputs must be tied to VSS for correct XNOR functionality, per device-specific biasing requirements.

FAQ

What is the maximum operating temperature for NLV14077BDR2G?

The NLV14077BDR2G is rated for continuous operation from −55 °C to +125 °C ambient, validated per AEC-Q100 Grade 1 requirements. This specification applies across the full 3.0–18 VDC supply range and includes derating of power dissipation above 65 °C. The NLV14077BDR2G maintains guaranteed VOH/VOL and propagation delay performance throughout this range, making it suitable for under-hood automotive applications.

Is NLV14077BDR2G pin-compatible with CD4077B?

Yes, the NLV14077BDR2G is pin-compatible with CD4077B and functions as a direct replacement. Both devices use identical SOIC-14 pin assignments: VDD on pin 14, VSS on pin 7, and matching XNOR input/output mapping across pins 1–13. The NLV14077BDR2G retains the same logic truth table, input thresholds, and output drive capability while adding AEC-Q100 qualification and Pb-free packaging.

Does NLV14077BDR2G require external pull-up or pull-down resistors on unused inputs?

Yes, unused inputs on the NLV14077BDR2G must be tied to a defined logic level-specifically to VSS (ground) for correct XNOR operation. Leaving inputs floating risks increased supply current, erratic output behavior, or latch-up due to the high-impedance CMOS structure. The NLV14077BDR2G datasheet explicitly mandates this practice to ensure stable DC operation and noise immunity.

What is the minimum supply voltage required for NLV14077BDR2G to meet its specified output drive?

The NLV14077BDR2G guarantees ±0.64 mA output drive at VDD = 5.0 VDC, with performance scaling linearly down to 3.0 VDC. At 3.0 V, the minimum guaranteed sink current is ±0.36 mA and source current is −0.36 mA, sufficient to drive modern low-power logic families. The NLV14077BDR2G remains fully functional across the entire 3.0–18 V range, with VOH/VOL and propagation delay specifications maintained at all voltages.

Can NLV14077BDR2G be used in place of NLV14070BDR2G in an existing design?

No-NLV14077BDR2G implements quad exclusive NOR (XNOR) logic, whereas NLV14070BDR2G implements quad exclusive OR (XOR). Their truth tables are complements: XNOR outputs HIGH when inputs match; XOR outputs HIGH when inputs differ. Swapping them without inverting downstream logic will invert system behavior. The NLV14077BDR2G cannot substitute for NLV14070BDR2G unless the application specifically requires inverted logic polarity.
