Texas Instruments SN74LVC827APW

Overview

SN74LVC827APW from Texas Instruments is a 10-bit noninverting buffer/driver with dual 3-state outputs, designed for 1.65 V to 3.6 V V_CC operation. It delivers 24 mA output drive at 3.3 V, supports 5.5-V-tolerant inputs, and achieves 6.7 ns propagation delay at 3.3 V - enabling high-speed bus interfacing in mixed-voltage systems such as LED display drivers and telecom infrastructure backplanes.

For engineers reviewing the SN74LVC827APW datasheet, SN74LVC827APW pinout, SN74LVC827APW application, or SN74LVC827APW equivalent, key selection criteria include its dual OE-controlled 3-state operation, I_off support for live insertion, ±50 mA output current rating, and TSSOP-24 package compatibility with space-constrained industrial PCB layouts.

Technical Context

The SN74LVC827APW implements a dual-gated 3-state control architecture: OE1 and OE2 feed an internal 2-input AND gate with active-low logic, so either OE high forces all ten Y outputs into high-impedance. Its CMOS design enables true data buffering (noninverting) with balanced rise/fall times and supports down-translation from 5-V inputs to 3.3-V or 1.8-V buses.

It features I_off circuitry that disables outputs and blocks current backflow when V_CC = 0 V, satisfying partial-power-down requirements. Input tolerance up to 5.5 V and ESD ratings of 2000 V HBM / 1000 V CDM ensure robustness in noisy industrial environments without external protection.

FAQ

What is the maximum operating temperature for the SN74LVC827APW?

The SN74LVC827APW is rated for operation from –40°C to +125°C ambient temperature, fully specified across this range per its Recommended Operating Conditions table. This makes SN74LVC827APW suitable for under-hood automotive modules, industrial PLCs, and telecom base station hardware where thermal stress is a primary reliability concern.

Does the SN74LVC827APW support 5-V input signals while powered from 3.3 V?

Yes, the SN74LVC827APW accepts input voltages up to 5.5 V regardless of V_CC level - including when V_CC = 3.3 V. This 5-V-tolerant input capability is explicitly guaranteed in the datasheet and enables direct interfacing with legacy 5-V logic without external level-shifting circuitry, a key feature of the SN74LVC827APW.

How does the dual output-enable (OE1/OE2) structure function in the SN74LVC827APW?

The SN74LVC827APW uses an internal 2-input AND gate with active-low logic: both OE1 and OE2 must be low to enable outputs. If either OE1 or OE2 is high, all ten Y outputs enter high-impedance state. This architecture provides redundant control - for example, OE1 for local microcontroller control and OE2 for system-level fault shutdown - enhancing functional safety in the SN74LVC827APW.

Can the SN74LVC827APW be used in hot-swap applications?

Yes, the SN74LVC827APW incorporates I_off circuitry that disables outputs and blocks current backflow when V_CC = 0 V. This feature is explicitly validated per JESD78 and supports safe live insertion in modular backplanes and field-replaceable units - a core capability confirmed for the SN74LVC827APW in TI's device functional modes documentation.

What is the typical propagation delay of the SN74LVC827APW at 3.3 V?

The SN74LVC827APW achieves a typical propagation delay (t_pd) of 6.7 ns at V_CC = 3.3 V, as measured under standard load conditions (30 pF, ±0.3 V swing). This value is guaranteed maximum across –40°C to +85°C and remains ≤7.9 ns up to +125°C - confirming consistent high-speed performance in the SN74LVC827APW across its full industrial temperature range.
