Texas Instruments SN74LVC827ADGVR

Overview

SN74LVC827ADGVR from Texas Instruments is a 10-bit noninverting buffer/driver with 3-state outputs, designed for 1.65 V to 3.6 V V_CC operation. It features dual active-low output-enable inputs (OE1, OE2), 5.5-V-tolerant inputs, 24 mA output drive at 3.3 V, and 6.7 ns typical propagation delay - enabling high-speed bus interfacing in mixed-voltage systems such as LED display drivers and telecom backplanes.

For engineers reviewing the SN74LVC827ADGVR datasheet, SN74LVC827ADGVR pinout, SN74LVC827ADGVR application, or SN74LVC827ADGVR equivalent, key selection criteria include its I_off support for live insertion, ±24 mA drive capability per output, 3.3-V/5-V mixed-mode compatibility, and TVSOP-24 package suitability for space-constrained industrial PCBs.

Technical Context

The SN74LVC827ADGVR implements a dual-gated 3-state control architecture: both OE1 and OE2 must be low to enable all ten Y outputs; either high forces all outputs into high-impedance. Its CMOS design supports true data buffering without inversion, and input tolerance up to 5.5 V allows direct interfacing with legacy 5-V logic while powered from 3.3 V.

It integrates I_off circuitry that disables outputs and blocks current flow when V_CC = 0 V, preventing back-drive damage during partial power-down. Latch-up performance exceeds 250 mA per JESD17, and ESD protection meets 2000-V HBM, 1000-V CDM, and 200-V MM standards.

FAQ

What is the maximum operating voltage for SN74LVC827ADGVR inputs?

The SN74LVC827ADGVR inputs tolerate up to 5.5 V regardless of V_CC level - a key feature enabling direct interfacing with 5-V logic families while operating from 1.65–3.6 V supplies. This specification is validated across –40°C to +125°C and is explicitly defined in the Recommended Operating Conditions table of the official datasheet (SCAS306K).

Does SN74LVC827ADGVR support hot-swap or live-insertion applications?

Yes, SN74LVC827ADGVR supports live insertion via its I_off feature, which disables outputs and limits I/O leakage to <±10 µA when V_CC = 0 V. This prevents damaging back-current flow during partial power-down - a requirement verified per JESD78 and confirmed in Section 9.3 of the SN74LVC827ADGVR datasheet.

What is the typical propagation delay of SN74LVC827ADGVR at 3.3 V?

The typical propagation delay (t_pd) of SN74LVC827ADGVR is 6.7 ns at V_CC = 3.3 V, TA = 25°C, as measured from A to Y under load conditions specified in Figure 3 of the datasheet. This value is guaranteed ≤7.9 ns across –40°C to +125°C and forms the basis for timing margin calculations in high-speed bus designs.

Can SN74LVC827ADGVR drive standard TTL loads directly?

Yes, SN74LVC827ADGVR can drive standard TTL loads directly: at V_CC = 3.3 V, it delivers ±24 mA per output - sufficient to sink/source current for ≥10 LSTTL loads (each requiring ~0.4 mA). This capability is confirmed in the Electrical Characteristics table (Section 7.5) and eliminates need for external buffer stages in most industrial control applications.

What package type does SN74LVC827ADGVR use, and what are its key mechanical dimensions?

SN74LVC827ADGVR uses a 24-pin TVSOP (Thin Very Small Outline Package) with JEDEC MO-175AA registration. Its nominal body size is 5.00 mm × 4.40 mm, thickness ≤1.2 mm, and 0.4 mm lead pitch - making it significantly smaller than SSOP or SOIC variants while maintaining compatibility with standard SMT reflow profiles (MSL Level-1, 260°C peak).
