Texas Instruments SN74LVC1G86DBVR

Overview

SN74LVC1G86DBVR from Texas Instruments is a single 2-input exclusive-OR gate IC performing Y = AB + ĀB in positive logic, designed for 1.65V–5.5V operation with ±24mA output drive at 3.3V, 4ns max propagation delay at 3.3V/15pF, and Ioff-enabled partial-power-down protection. It serves as a true/complement selector in bus interface and level translation circuits.

For engineers reviewing the SN74LVC1G86DBVR datasheet, SN74LVC1G86DBVR pinout, SN74LVC1G86DBVR application, or SN74LVC1G86DBVR equivalent, key selection criteria include overvoltage-tolerant inputs (up to 5.5V), nanosecond-level timing performance across 1.65–5.5V supply range, SOT-23 (DBV) package compatibility, and Ioff support for hot-swap and power-gating systems.

Technical Context

This device implements standard CMOS XOR logic with balanced push-pull outputs capable of sourcing/sinking ±24mA at 3.3V and ±32mA at 4.5V. Its input structure supports overvoltage tolerance up to 5.5V independent of VCC, enabling robust down-translation between voltage domains.

The Ioff feature disables all outputs when VCC = 0V, limiting leakage to ±10µA and preventing back-drive current-critical for partial-power-down architectures. Input transition rate requirements (e.g., 10ns/V at 3.3V) ensure reliable switching without oscillation under fast-edge conditions.

FAQ

What is the maximum input voltage the SN74LVC1G86DBVR can tolerate?

The SN74LVC1G86DBVR supports input voltages up to 5.5V regardless of VCC level, enabling direct interfacing with 5V systems while operating from 1.65V–3.3V supplies. This overvoltage tolerance is explicitly specified in Section 5.3 of the datasheet and applies to both A and B inputs. The SN74LVC1G86DBVR maintains full functionality and does not require external clamping diodes when driven by 5V signals.

Does the SN74LVC1G86DBVR support partial power-down operation?

Yes, the SN74LVC1G86DBVR implements Ioff circuitry that places all outputs in high-impedance state when VCC = 0V, limiting leakage current to ±10µA per pin. This feature is fully characterized per JESD78 Class II latch-up standards and enables safe hot-swap, power sequencing, and standby modes. The SN74LVC1G86DBVR remains protected against damaging back-drive current even when other system rails remain active.

What is the propagation delay of the SN74LVC1G86DBVR at 3.3V supply?

The SN74LVC1G86DBVR has a maximum propagation delay (tpd) of 4ns at VCC = 3.3V with a 15pF capacitive load and operating temperature of –40°C to +85°C. At the extended –40°C to +125°C range, tpd increases to 4.5ns under identical conditions. These values are measured from input transition (10%–90%) to output transition (50%) and are guaranteed across process, voltage, and temperature corners.

Which package type does the SN74LVC1G86DBVR use?

The SN74LVC1G86DBVR uses the SOT-23 (DBV) 5-pin package with dimensions of 2.90mm × 1.60mm. It features gull-wing leads compatible with standard reflow soldering processes and carries a Level-1 MSL rating (unlimited floor life at ≤30°C/60% RH). The "DBV" suffix in the part number explicitly denotes this package variant, confirmed in TI's Package Option Addendum.

Can the SN74LVC1G86DBVR operate at 1.8V supply voltage?

Yes, the SN74LVC1G86DBVR is fully specified for operation from 1.65V to 5.5V, including 1.8V nominal supply. At 1.8V, it delivers 2.1ns minimum to 9.1ns maximum tpd (CL = 15pF), supports ±4mA output drive, and maintains VIH/VIL thresholds scaled to 0.65×VCC and 0.35×VCC respectively. All AC and DC parameters in Sections 5.5–5.7 of the datasheet apply across this full voltage range.
