Product details

Overview

SN74LVC828APWT 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 in mixed-voltage bus interfaces. It supports 5-V-tolerant inputs, delivers ≤6.7 ns propagation delay at 3.3 V, and provides ±24 mA output drive for wide data-path buffering in industrial control backplanes.

For engineers reviewing the SN74LVC828APWT datasheet, SN74LVC828APWT pinout, SN74LVC828APWT application, or SN74LVC828APWT equivalent, key selection criteria include its dual active-low 3-state control logic, I_off partial-power-down capability, 5.5-V input tolerance, and TVSOP-24 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC828APWT implements a dual-input AND gate for 3-state control: both OE1 and OE2 must be low to enable outputs; either high forces all ten Y outputs into high-impedance. Its inputs accept up to 5.5 V regardless of V_CC, enabling direct interfacing between 3.3-V logic and legacy 5-V systems without level shifters.

It features I_off circuitry that disables outputs during power-down to prevent backflow current, and meets JESD 17 latch-up immunity (>250 mA). Output ground bounce (V_OLP) and undershoot (V_OHV) are characterized at <0.8 V and >2 V respectively under 3.3-V/25°C conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 3.6 V - Enables operation across low-voltage microcontroller I/O domains and mixed-supply systems.
Input Voltage Tolerance	Up to 5.5 V - Allows direct connection to 5-V sources without external clamping or translation.
t_pd (Max)	6.7 ns at V_CC = 3.3 V - Supports ≥100 MHz bus timing margins in high-speed data paths.
I_OL/I_OH	±24 mA at V_CC = 3.0 V - Drives heavy capacitive loads or multiple CMOS inputs per channel.
I_off	±10 µA at V_CC = 0 V - Prevents damaging current flow during hot-insertion or partial power-down sequences.
ESD Rating	2000-V HBM - Meets industrial-grade robustness requirements for board-level handling and field deployment.
Operating Temperature	–40°C to +85°C - Qualified for extended-temperature industrial and automotive under-hood applications.

Pinout & Package

SN74LVC828APWT uses a 24-pin TVSOP (Thin Very Small Outline Package) with 0.4-mm lead pitch, 6.6-mm body width, and 1.2-mm maximum height - optimized for space-constrained PCBs requiring thermal efficiency and automated assembly compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8, 9, 10	A1–A10 Inputs	Inverting data inputs; tolerate 5.5 V independent of V_CC; drive internal buffers.
11, 12	OE1, OE2	Active-low 3-state enables; AND logic - both must be low to activate outputs.
13	GND	Ground reference for all logic and output stages; decoupling required near pin.
14	V_CC	Supply voltage (1.65–3.6 V); powers internal logic and output drivers.
15–24	Y1–Y10 Outputs	Inverted buffered outputs; 3-state capable; ±24 mA drive; 5.5-V tolerant in high-Z state.

Key Features

Feature	Design Value
Mixed-mode signal operation	5-V input compatibility with 3.3-V V_CC eliminates need for discrete level translators in hybrid voltage systems.
Dual 3-state enable architecture	Independent OE1/OE2 pins allow flexible bus arbitration and multi-master control without external logic.
I_off partial-power-down support	Outputs disable safely during V_CC ramp-down, preventing backfeed into powered subsystems in modular designs.
Low dynamic power dissipation	7 pF typical C_pd per buffer in disabled state - reduces switching noise and system-level EMI.
Robust ESD protection	2000-V HBM rating ensures reliability during manufacturing, handling, and field service without added protection components.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC827APWT	Non-inverting output polarity; identical pinout, V_CC, drive strength, and timing.	Required where signal inversion would disrupt protocol handshaking or data alignment.	Select when system logic requires true (non-inverted) data path replication.
SN74ALVC16835DGGR	16-bit, non-inverting, higher drive (±24 mA), but larger 48-pin TSSOP package and 2.3–3.6 V only V_CC.	Suitable for wider buses but incompatible with 1.65–2.2 V operation and space-constrained layouts.	Choose only if 16-bit width and higher noise immunity outweigh footprint and voltage-range constraints.

Compared with SN74LVC828APWT, SN74LVC827APWT offers functional equivalence except for output polarity, making it a drop-in replacement where inversion is undesirable; SN74ALVC16835DGGR expands bit width and noise margin but sacrifices voltage flexibility and board area efficiency.

FAQ

What is the function of OE1 and OE2 on the SN74LVC828APWT?

The SN74LVC828APWT uses OE1 and OE2 as active-low, dual-input AND-gated 3-state enables: both pins must be driven low to activate the ten inverting outputs. If either OE1 or OE2 is high, all Y1–Y10 outputs enter high-impedance mode - enabling flexible bus sharing and multi-controller arbitration without external logic gates.

Can SN74LVC828APWT operate with a 1.8-V supply and interface to 5-V inputs?

Yes. The SN74LVC828APWT is fully specified for V_CC from 1.65 V to 3.6 V and accepts input voltages up to 5.5 V regardless of supply level. At 1.8 V V_CC, it maintains valid logic thresholds (VIH = 1.17 V min, VIL = 0.63 V max) and retains 5-V input tolerance - making it ideal for bridging legacy 5-V peripherals to modern low-voltage MCUs.

Does SN74LVC828APWT support partial power-down, and how is it implemented?

Yes. The SN74LVC828APWT integrates I_off circuitry that disables outputs when V_CC = 0 V, limiting leakage to ±10 µA. This prevents reverse current flow from live buses into unpowered sections - critical for hot-swap, modular power architectures, and systems with staggered power sequencing. No external components are needed to enable this feature.

What is the maximum output drive capability of SN74LVC828APWT at 3.3 V?

At V_CC = 3.3 V, the SN74LVC828APWT delivers ±24 mA per output (I_OH/I_OL) under DC conditions. This allows direct driving of multiple 74LVC inputs, termination resistors, or moderate capacitive loads (up to ~30 pF) while maintaining VOL ≤ 0.55 V and VOH ≥ 2.2 V - verified across –40°C to +85°C.

Is SN74LVC828APWT pin-compatible with other packages in the same family?

No. While SN74LVC828APWT (TVSOP-24) shares identical logic, electrical specs, and pin functions with SN74LVC828ADW (SOIC-24) and SN74LVC828APW (TSSOP-24), the TVSOP package has a finer 0.4-mm lead pitch versus 0.65 mm for TSSOP and 1.27 mm for SOIC. PCB layout and stencil design must be re-optimized - it is not a drop-in mechanical replacement.
