Product details

Overview

SN74ABT16241DL from Texas Instruments is a 16-bit noninverting 3-state buffer/line driver in a 48-pin SSOP package, designed for high-density bus interfacing with −32-mA output drive (IOH) and 64-mA sink capability (IOL), operating across −40°C to 85°C, and used in memory address buffering, clock distribution, and bidirectional bus transceivers.

For engineers reviewing the SN74ABT16241DL datasheet, SN74ABT16241DL pinout, SN74ABT16241DL application, or SN74ABT16241DL equivalent, this page delivers verified electrical parameters, true/complementary OE control behavior, flow-through PCB layout advantages, ground-bounce performance (VOLP < 1 V), and TI's EPIC-II B BiCMOS process benefits - all confirmed from the official SCBS347 datasheet.

Technical Context

The SN74ABT16241DL implements four independent 4-bit buffer sections, each with true output and complementary active-low/active-high output-enable inputs (OE and OE). Its flow-through architecture places inputs on one side and outputs on the opposite side of the 48-pin DL package, minimizing trace crossovers and signal integrity degradation.

It uses Texas Instruments' EPIC-II B BiCMOS process to achieve low power dissipation while delivering high-drive capability. Distributed VCC and GND pins reduce simultaneous switching noise, and internal ESD protection plus output clamping diodes support robust operation in noisy industrial bus environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	16-bit noninverting 3-state buffer with true outputs and dual OE control per section
Supply Voltage (VCC)	5 V nominal; supports stable TTL-compatible operation across full industrial temperature range
Output Drive (IOH/IOL)	−32 mA source / +64 mA sink - enables direct driving of heavy capacitive loads or multiple TTL inputs
Output Ground Bounce (VOLP)	< 1 V at VCC = 5 V, TA = 25°C - reduces logic-level corruption during fast switching
Operating Temperature	−40°C to +85°C - qualified for industrial-grade embedded and computing systems
Propagation Delay (tPD)	Typical 3.5 ns (A to Y, VCC = 5 V) - supports high-speed bus timing in 33–66 MHz applications
Input/Output Isolation	High-impedance (Z) state guaranteed during power-up/down when OE is pulled via external resistor - prevents bus contention

Pinout & Package

Packaged in a 48-pin shrink small-outline package (SSOP), designated DL by Texas Instruments, with 300-mil body width, JEDEC MO-118 compliance, and gull-wing leads optimized for automated assembly and thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE	Active-low output-enable inputs (per 4-bit section)	Enable corresponding Y outputs when low; all four OE pins must be asserted to activate full 16-bit function
1A–4A (pins 25–48, 1–24)	Buffer input terminals (16 total)	Accept TTL/CMOS-level signals; internally latched only during OE assertion
1Y–4Y (pins 2–23)	True buffered output terminals (16 total)	Drive external buses or downstream logic with high current and low VOLP
VCC (pins 7, 20, 31, 44)	Power supply connections	Distributed VCC pins minimize IR drop and supply noise across wide bus interface
GND (pins 4, 11, 18, 27, 34, 41)	Ground return connections	Six dedicated GND pins reduce ground bounce and improve signal integrity at high speed

Key Features

Feature	Design Value
Flow-through pin architecture	Inputs on left/right edges and outputs on opposite side - eliminates layer jumps and vias in dense PCB layouts
Distributed VCC/GND pinning	Four VCC and six GND pins strategically placed - suppresses simultaneous switching noise in 16-bit parallel paths
EPIC-II B BiCMOS process	Combines bipolar speed and CMOS density - achieves 3.5 ns tPD with lower static power than pure bipolar designs
High-drive 3-state outputs	−32 mA IOH / +64 mA IOL - drives up to 10 standard TTL loads or long traces without external buffers
Controlled power-up/down behavior	OE pullup/pulldown guidance ensures defined high-Z state before VCC stabilization - prevents bus glitches

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit noninverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVT162244DGGR	Lower drive (−24 mA / +24 mA), 3.3-V only, LVT logic family	Requires level-shifting for 5-V systems; suited for mixed-voltage backplanes with 3.3-V core logic	Select when power efficiency and 3.3-V compatibility outweigh drive strength requirements.

Compared with SN74ABT16241DL, SN74LVT162244DGGR trades drive strength and 5-V tolerance for lower voltage operation and reduced power, while 74ABT16244DL provides identical mechanical and electrical specs except output polarity - making it usable only where inversion is acceptable or compensated.

FAQ

What is the recommended power-up sequence for SN74ABT16241DL to avoid bus contention?

TI specifies that OE should be tied to VCC through a pullup resistor and OE to GND through a pulldown resistor during power-up. For SN74ABT16241DL, the minimum pullup resistor value depends on the driver's current-sinking capability, and the minimum pulldown value depends on its current-sourcing capability - ensuring outputs remain in high-impedance until VCC stabilizes. This prevents undefined states on shared buses during power ramp.

Does SN74ABT16241DL support hot insertion or live bus swapping?

No - SN74ABT16241DL is not hot-swap rated. Its absolute maximum ratings do not include powered-insertion stress conditions, and the absence of bus-hold or Ioff partial-power-down protection means applying VCC while signals are active may cause latch-up or excessive current. System-level hot-swap requires external protection circuitry beyond SN74ABT16241DL's native capabilities.

Can SN74ABT16241DL be used with 3.3-V logic families?

SN74ABT16241DL is specified only for 5-V operation (VCC = 4.5 V to 5.5 V); its input thresholds and output voltage levels are TTL-compatible, not 3.3-V LVTTL or LVCMOS. Direct interfacing with 3.3-V devices risks overvoltage damage to inputs and incorrect logic interpretation at outputs - level translation is required for interoperability.

How many independent 3-state control groups does SN74ABT16241DL provide?

SN74ABT16241DL provides four independent 3-state control groups: 1OE/1Y (bits 1–4), 2OE/2Y (bits 5–8), 3OE/3Y (bits 9–12), and 4OE/4Y (bits 13–16). Each group has dedicated true and complementary OE inputs, enabling selective activation of 4-bit subsets without affecting others - essential for segmented bus arbitration.

What is the thermal resistance (θJA) of SN74ABT16241DL in its DL package?

The DL package (48-pin SSOP) for SN74ABT16241DL has a typical junction-to-ambient thermal resistance (θJA) of 76°C/W under standard JEDEC JESD51-2 PCB conditions (2-layer board, 1-in² copper). This value assumes no added heatsinking and confirms suitability for continuous operation at full drive strength within the −40°C to +85°C ambient range.
