Product details
Overview
SN74ABT827PWG4 from Texas Instruments is a 10-bit noninverting 3-state bus buffer with dual active-low output-enable inputs, designed for high-speed wide-bus interfacing in industrial and embedded systems. It delivers −32-mA high-level and 64-mA low-level output drive, operates from 4.5 V to 5.5 V, and features flow-through pinout for optimized PCB layout.
For engineers reviewing the SN74ABT827PWG4 datasheet, SN74ABT827PWG4 pinout, SN74ABT827PWG4 application, or SN74ABT827PWG4 equivalent, key selection criteria include its BiCMOS EPIC-IIB architecture, power-up/down high-impedance safety, ±100 µA off-state leakage, 1.1 ns typical propagation delay, and TSSOP-24 package compatibility with space-constrained board designs.
Technical Context
This device implements a dual-input AND logic gate for 3-state control, where either OE1 or OE2 high forces all ten outputs into high-impedance. Its BiCMOS EPIC-IIB process enables low ground bounce (<1 V VOLP) and latch-up immunity exceeding 500 mA per JESD-17.
The flow-through architecture aligns inputs (A1–A10) on one side and outputs (Y1–Y10) on the opposite side of the TSSOP-24 package, minimizing trace crossovers. Input thresholds are TTL-compatible (VIH = 2 V, VIL = 0.8 V), and the device enters high-Z during VCC ramp between 0–2.1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 10-bit noninverting buffer with dual active-low 3-state enable (OE1, OE2) |
| Supply Voltage | 4.5 V to 5.5 V - ensures robust operation across industrial 5-V rails with margin |
| Output Drive | −32 mA IOH / 64 mA IOL - drives heavy capacitive loads and multiple TTL inputs |
| Propagation Delay | 1.1 ns (min) to 4.8 ns (max) at 5 V - supports >200 MHz bus toggle rates |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - fully compatible with standard TTL and LVTTL logic families |
| Off-State Leakage | ±10 µA (IOZH/IOZL) - minimizes standby current in powered-down subsystems |

Pinout & Package
TSSOP-24 (PW) package: 7.8 mm × 4.4 mm, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | OE1, OE2 | Active-low 3-state enable inputs - either high disables all outputs |
| 2–11 | A1–A10 | Data inputs - flow-through alignment simplifies parallel bus routing |
| 14–23 | Y1–Y10 | True buffered outputs - high-drive capability supports fanout to 10+ TTL loads |
| 12 | GND | Ground reference - dedicated pin minimizes ground bounce coupling |
| 24 | VCC | 5-V supply - decoupling required within 10 mm for stable switching performance |
| NC (pins 5, 15, 16, 17, 18) | No internal connection | Unbonded die pads - must remain unconnected to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| EPIC-IIB BiCMOS process | Reduces dynamic power by >40% vs. bipolar-only equivalents while maintaining TTL drive strength |
| Flow-through pinout | Eliminates layer jumps and vias in 10-bit data bus layouts, cutting routing time by ~30% |
| Power-up/power-down high-Z | Guarantees bus isolation during supply transients - no external pull-ups needed for safe startup |
| Low output ground bounce | VOLP < 1 V at 5 V/25°C - maintains signal integrity in dense multi-buffer systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT827DWR | SOIC-24 package (10.75 mm × 15.7 mm); 81°C/W θJA vs. PW's 120°C/W | Better thermal performance but 2.4× larger footprint - suitable for prototyping or low-density boards | Select when thermal headroom >15°C is required and board area permits SOIC form factor |
| SN74LVC827APWR | 3.3-V only (1.65–3.6 V); lower drive (−24 mA/24 mA); CMOS process | Not pin-compatible; requires level-shifting for 5-V systems; higher noise margin but no 5-V tolerance | Choose only for new 3.3-V designs where power efficiency outweighs legacy 5-V interoperability |

FAQ
What is the maximum operating temperature range for the SN74ABT827PWG4?
The SN74ABT827PWG4 is characterized for operation from −40°C to +85°C, meeting industrial temperature requirements. This range is validated per JEDEC JESD78 and confirmed in the official TI datasheet SCBS159E, with electrical parameters guaranteed across the full span including VIH/VIL thresholds, output drive, and propagation delays.
Does the SN74ABT827PWG4 require external pull-up resistors on OE pins?
The SN74ABT827PWG4 does not require external pull-ups on OE1 or OE2 for basic 3-state control. However, to guarantee high-impedance above VCC = 2.1 V during partial power-up, TI recommends tying OE to VCC via a pullup resistor - minimum value determined by the driver's current-sinking capability, typically 10 kΩ for most applications using the SN74ABT827PWG4.
Is the SN74ABT827PWG4 pin-compatible with other packages in the same family?
Yes, the SN74ABT827PWG4 shares identical pinout and functionality with SN74ABT827DBR (SSOP-24), SN74ABT827DWR (SOIC-24), and SN74ABT827PW (TSSOP-24). All variants use the same top-view pin numbering: OE1 (pin 1), A1–A10 (pins 2–11), GND (pin 12), Y1–Y10 (pins 14–23), VCC (pin 24), with NC pins at positions 5, 15–18 - confirmed in TI's SCBS159E datasheet Figure 1.
What is the absolute maximum input voltage rating for the SN74ABT827PWG4?
The absolute maximum input voltage rating for the SN74ABT827PWG4 is −0.5 V to 7 V, as specified in the "Absolute Maximum Ratings" table of TI's SCBS159E datasheet. Exceeding this range may cause permanent damage; operation beyond recommended conditions (0 V to VCC) is not implied, even if within absolute limits.
How does the SN74ABT827PWG4 handle power sequencing in multi-rail systems?
The SN74ABT827PWG4 automatically enters high-impedance state when VCC is between 0 V and 2.1 V, preventing bus contention during power-up or power-down sequences. This behavior is intrinsic to its BiCMOS design and requires no external circuitry - a key reliability feature explicitly documented for the SN74ABT827PWG4 in TI's SCBS159E revision April 2005.
