Product details

Overview

74LVC827AD from Nexperia is a 10-bit non-inverting buffer/line driver with dual 3-state enable (OE1, OE2) and 5 V tolerant inputs/outputs. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V logic domains, and is rated for −40 °C to +125 °C operation in SO24 package. Used in bus interface and level-shifting applications in industrial control backplanes.

For engineers reviewing the 74LVC827AD datasheet, 74LVC827AD pinout, 74LVC827AD application, or 74LVC827AD equivalent, key selection considerations include 5 V tolerance on all I/O pins, propagation delay ≤6.7 ns at 3.3 V, dual independent output enables, 3-state leakage <±5 µA at 5.5 V, and JEDEC-compliant voltage ranges across JESD8-7A/5A/C standards.

Technical Context

This device implements ten independent buffer channels with active-low dual enable control (OE1 and OE2), where either enable LOW activates outputs and both HIGH place all Y[0:9] in high-impedance state. The architecture supports bidirectional voltage translation: inputs accept 0–5.5 V regardless of VCC (1.2–3.6 V), and outputs tolerate up to 5.5 V in 3-state mode.

It complies with multiple JEDEC standards (JESD8-7A, -5A, -C/JESD36) across overlapping VCC ranges and features robust ESD protection: >2000 V HBM, >200 V MM, and >1000 V CDM. Static drive capability includes ±24 mA output current at 3.0 V with VOL ≤0.55 V and VOH ≥2.25 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - Enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic systems.
I/O Voltage Tolerance	0 V to 5.5 V - Allows safe connection to 5 V buses without external level shifters or clamping diodes.
Propagation Delay (tpd)	1.0 ns (min) to 6.7 ns (max) at VCC = 3.0–3.6 V - Supports high-speed data routing in 33 MHz+ parallel interfaces.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or 10 LVTTL loads simultaneously.
3-State Leakage (IOZ)	±5 µA max at VO = 5.5 V - Ensures minimal bus contention during disable in hot-swap or shared-bus configurations.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives.
ESD Protection	HBM >2000 V, MM >200 V, CDM >1000 V - Meets IEC 61000-4-2 system-level ESD immunity requirements.

Pinout & Package

74LVC827AD is housed in SO24 plastic small outline package (SOT137-1), 24-pin, 7.5 mm body width, 1.27 mm pitch, with standard pin 1 index marking.

Pin/Terminal	Circuit Role	Design Meaning
1, 13	OE1, OE2	Active-low output enable inputs - Either LOW enables all 10 outputs; both HIGH forces all Y[0:9] into high-Z.
2–11	A0–A9	Buffer input terminals - Accept 0–5.5 V logic signals independent of VCC; no level-shifter circuitry required.
14–23	Y0–Y9	Buffer output terminals - Deliver rail-to-rail CMOS outputs with 5 V tolerance in 3-state; support bus hold when disabled.
12	GND	Ground reference - Shared return path for all I/O and supply currents; decoupling capacitor must be placed adjacent.
24	VCC	Power supply - Supplies internal logic and output drivers; requires local 100 nF ceramic bypass near pin.

Key Features

Feature	Design Value
5 V tolerant I/O	Enables direct connection to legacy 5 V microcontrollers or FPGAs without external translators or resistors.
Dual independent enables	Allows partitioned bus control - e.g., OE1 manages lower byte (Y0–Y4), OE2 manages upper byte (Y5–Y9) in split-data-path designs.
Wide VCC range (1.2–3.6 V)	Supports battery-powered IoT nodes down to 1.2 V core voltage while maintaining full 5 V I/O compatibility.
Low static ICC (≤40 µA)	Reduces quiescent power in always-on subsystems such as watchdog interfaces or sensor hub buffers.
JEDEC-compliant voltage specs	Guarantees interoperability across vendor ecosystems using JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C (2.7–3.6 V).

Applications

Industrial PLC Backplane Interface

Automotive Body Control Module (BCM) Data Bus

Use Scenario: Isolating and translating address/data lines between 3.3 V MCU and 5 V peripheral ASIC on a DIN-rail mounted PLC carrier board.

IC Role / Device Role / Timing Role: 10-bit unidirectional buffer with dual enable control synchronizes with CPU write strobe to gate data onto shared 5 V bus.

Use Value: Eliminates need for discrete MOSFET translators; 6.7 ns tpd ensures setup/hold timing margin at 33 MHz bus clock.

Use Scenario: Driving LIN or CAN transceiver control signals from a 1.8 V domain MCU in a BCM housing exposed to under-hood temperature extremes.

IC Role / Device Role / Timing Role: Level-shifting buffer for enable/disable control lines to isolated power domains, operating continuously at +125 °C ambient.

Use Value: 5 V tolerant outputs withstand load-dump transients up to 5.5 V; −40 °C to +125 °C rating avoids derating or thermal throttling.

Test Equipment Digital I/O Expansion

Medical Diagnostic Imaging Subsystem

Use Scenario: Adding 10-bit parallel digital I/O to a PXIe-based automated test system where FPGA I/O banks run at 2.5 V but DUTs require 5 V TTL signaling.

IC Role / Device Role / Timing Role: Bidirectional voltage translator enabling FPGA to source/sink 5 V logic levels without violating its 2.5 V I/O limits.

Use Value: Input clamping current ≤50 mA prevents FPGA damage during overvoltage events; 1.0 ns min tpd preserves signal integrity at 100 MHz sampling rates.

Use Scenario: Buffering real-time pixel data streams from a 3.3 V image sensor ASIC to a 5 V analog front-end (AFE) ADC interface in portable ultrasound equipment.

IC Role / Device Role / Timing Role: High-speed data pipeline buffer with low skew (<1.5 ns) ensuring simultaneous latching of 10-bit pixel words across all channels.

Use Value: Output skew guarantee eliminates inter-channel timing jitter; ±24 mA drive sustains signal integrity over 15 cm FR4 traces to ADC inputs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 10-bit buffer/level-shifter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC827APW	TSSOP24 package (4.4 mm width); identical electrical specs and pinout.	Better suited for space-constrained PCBs; thermal resistance higher than SO24 (5.5 mW/K derating above 60 °C vs. 8 mW/K at 70 °C).	Select when board area is critical and thermal load is low; verify solder reflow profile compatibility with thinner leadframe.
74ALVC827M	Higher speed (tpd ≤4.2 ns at 3.3 V); wider VCC range (1.65–3.6 V only); no 1.2 V operation.	Optimized for high-frequency clock distribution; lacks 1.2 V support and −40 °C to +125 °C extended temp grade.	Choose only if design requires sub-5 ns propagation delay and operates strictly within 1.65–3.6 V; not suitable for ultra-low-power or extended-temp use.

Compared with SN74LVC827APW, the 74LVC827AD offers superior thermal performance in high-ambient environments due to SO24's lower junction-to-ambient resistance; versus 74ALVC827M, it provides broader voltage flexibility and extended temperature qualification at the cost of ~1.5 ns higher typical delay.

FAQ

Can 74LVC827AD operate with VCC = 1.2 V while driving 5 V-tolerant loads?

Yes. At VCC = 1.2 V, the device maintains full 5 V tolerance on all inputs and outputs per Table 4 limiting values. Inputs accept 0–5.5 V; outputs in 3-state tolerate 0–5.5 V. However, output drive strength drops to ±4 mA (VOH ≥1.08 V, VOL ≤0.12 V), so it is suitable only for high-impedance loads or short traces-not for driving 50 Ω lines or TTL fanouts at this voltage.

What is the maximum bus capacitance supported at 3.3 V with 24 mA drive?

At VCC = 3.3 V and IO = −24 mA, VOH ≥2.25 V and VOL ≤0.55 V per Table 6. Using the dynamic characteristic tpd ≤6.7 ns and output skew ≤1.5 ns, the device reliably drives ≤30 pF total load (including trace and receiver input capacitance) while maintaining signal integrity for 33 MHz parallel bus operation, as verified in Figure 6 test conditions.

How does dual enable (OE1/OE2) improve system-level fault containment?

OE1 and OE2 provide independent control over two logical groups of outputs - for example, Y0–Y4 and Y5–Y9. If one peripheral fails and pulls its bus segment low, disabling only its associated OE pin isolates that fault while keeping the other five lines operational. This enables graceful degradation in safety-critical subsystems without full bus shutdown.

Is 74LVC827AD qualified for automotive AEC-Q100?

No. Although rated for −40 °C to +125 °C operation, the 74LVC827AD is not AEC-Q100 qualified. Nexperia explicitly states in Section 15.3 that non-automotive qualified products are "neither qualified nor tested in accordance with automotive testing or application requirements." For automotive use, select the AEC-Q100 qualified 74LVC827AQ variant (if available) or consult Nexperia's automotive-grade portfolio.
