Texas Instruments SN74LVC828APWR

Overview

SN74LVC828APWR from Texas Instruments is a 10-bit inverting buffer/driver with dual 3-state enable inputs (OE1, OE2), designed for 1.65-V to 3.6-V V_CC operation and mixed-mode 3.3-V/5-V signal translation. It delivers 6.7 ns max propagation delay at 3.3 V, ±24 mA output drive, and supports partial-power-down via I_off. It is used in wide-data-path bus interfaces for industrial control backplanes and memory subsystems.

For engineers reviewing the SN74LVC828APWR datasheet, SN74LVC828APWR pinout, SN74LVC828APWR application, or SN74LVC828APWR equivalent, key selection criteria include its dual active-low 3-state control logic, 5.5-V-tolerant inputs, low ground bounce (<0.8 V), and TSSOP-24 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC828APWR implements a 10-channel inverting buffer architecture with two independent AND-gated 3-state enables: both OE1 and OE2 must be low to activate outputs; either high forces all Y1–Y10 into high-impedance. Its input structure accepts 0–5.5 V signals regardless of V_CC, enabling level translation between 3.3-V logic domains and legacy 5-V peripherals.

It features I_off circuitry that disables outputs during power-down to prevent backflow current, and meets JESD 17 latch-up immunity (>250 mA) and JESD 22 ESD ratings (2000-V HBM). Thermal resistance θ_JA is 88°C/W in the PW (TSSOP-24) package, validated per JEDEC MO-153.

Compared with SN74LVC828APWR, SN74LVC827APWR preserves input polarity but otherwise matches in timing, drive, and package-ideal for drop-in replacement where inversion is undesirable. The 74LVC244APWRE4 offers finer enable granularity at the cost of reduced channel count, supporting modular bus design where full 10-bit control is unnecessary.

FAQ

What is the logic function of the SN74LVC828APWR?

The SN74LVC828APWR is a 10-bit inverting buffer/driver with 3-state outputs. Each input A1–A10 drives an inverted output Y1–Y10. Outputs enter high-impedance when either OE1 or OE2 is high, due to internal AND logic. This behavior is confirmed in the functional table and logic diagram of the official TI datasheet SCAS347H.

Does the SN74LVC828APWR support 5-V input signals while powered from 3.3 V?

Yes, the SN74LVC828APWR accepts input voltages up to 5.5 V regardless of V_CC level (1.65–3.6 V), enabling seamless 5-V-to-3.3-V level translation. This is explicitly specified in the "Inputs Accept Voltages to 5.5 V" feature and validated in the Absolute Maximum Ratings and Recommended Operating Conditions tables.

What is the maximum propagation delay for the SN74LVC828APWR at 3.3 V?

The maximum propagation delay (t_pd) for the SN74LVC828APWR is 6.7 ns at V_CC = 3.3 V and T_A = 25°C, as measured from A to Y under standard load conditions. This value is documented in the Switching Characteristics table and applies across the full commercial temperature range (–40°C to 85°C) per derating curves.

Can the SN74LVC828APWR be used in partial-power-down applications?

Yes, the SN74LVC828APWR includes I_off circuitry that limits off-state current to ±10 µA when V_CC = 0 V, preventing damaging back-current flow. This capability is verified per JESD 78 and explicitly cited in the Features and Electrical Characteristics sections of the TI datasheet.

What package type is used for the SN74LVC828APWR?

The SN74LVC828APWR uses the TSSOP-24 (PW) package: 7.9 mm × 4.5 mm × 1.2 mm body, 0.65 mm lead pitch, gull-wing leads, JEDEC MO-153 compliant. This is confirmed in the Ordering Information table, Package Option Addendum, and PW0024A package outline drawing on ti.com.
