Product details

Overview

SN74ABT16240ADL from Texas Instruments is a 16-bit inverting buffer/driver with 3-state outputs, designed for high-density memory address and bus driving applications. It operates from 4.5 V to 5.5 V, delivers ±32 mA/±64 mA output drive, features flow-through pinout for optimized PCB layout, and is rated for –40°C to 85°C industrial temperature range.

For engineers reviewing the SN74ABT16240ADL datasheet, SN74ABT16240ADL pinout, SN74ABT16240ADL application, or SN74ABT16240ADL equivalent, this page provides verified functional identity, DL-package pin mapping, real-world timing (tPLH ≤ 4.7 ns), thermal resistance (θJA = 94°C/W), and validated drop-in alternatives for bus interface upgrades.

Technical Context

This device implements four independent 4-bit inverting buffers, each with symmetrical active-low output-enable (OE) control. Its EPIC-II^B BiCMOS architecture enables high-speed switching while minimizing ground bounce (VOLP < 1 V) and supply noise via distributed V_CC/GND pins.

The flow-through architecture aligns inputs on one side and outputs on the opposite side, reducing trace crossovers. Latch-up immunity exceeds 500 mA per JESD17, and ESD protection meets 2000 V (MIL-STD-883) and 200 V (machine model).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ABT16244ADL	Non-inverting output logic; identical pinout, drive strength, and timing specs.	Suitable where signal polarity must be preserved (e.g., direct address mirroring without logic inversion).	Select when system timing budget requires no additional inverter stage or when OE-controlled non-inverting buffering is required.
SN74LVC16244ADGGR	3.3-V only operation (1.65–3.6 V); lower drive (–24/+24 mA); TSSOP-48 package.	Targeted for low-power, mixed-signal SoC interfaces-not drop-in compatible with 5-V buses.	Choose for new 3.3-V designs prioritizing power efficiency over legacy 5-V compatibility; requires voltage translation for 5-V systems.

Compared with SN74ABT16244ADL and SN74LVC16244ADGGR, the SN74ABT16240ADL uniquely delivers 5-V tolerant inverting drive with 64-mA sink capability in the DL package-making it irreplaceable for legacy bus termination and high-noise industrial address buffering where polarity inversion is acceptable and voltage margin is critical.

FAQ

What is the operating temperature range for SN74ABT16240ADL?

The SN74ABT16240ADL is characterized for industrial operation from –40°C to +85°C. This range is validated per TI's recommended operating conditions and confirmed in the SCBS095G datasheet revision October 1998. The SN74ABT16240ADL maintains full electrical performance-including tPLH ≤ 4.7 ns and VOL ≤ 0.55 V-at both extremes of this range.

Does SN74ABT16240ADL support hot insertion or live insertion?

SN74ABT16240ADL does not include explicit hot-swap circuitry such as slew-rate control or undervoltage lockout. However, its high-impedance 3-state outputs, strong latch-up immunity (>500 mA), and 2000-V HBM ESD rating make it suitable for controlled hot-plug scenarios when OE is held high until power stabilization. The SN74ABT16240ADL datasheet recommends tying OE to V_CC via a pullup resistor to ensure high-Z state at power-up.

Can SN74ABT16240ADL drive a 50-pF load at 100 MHz?

Yes-the SN74ABT16240ADL switching characteristics are specified with CL = 50 pF, and its tPLH/tPHL values (1.0–4.7 ns) support reliable 100-MHz clock distribution or data strobing. At V_CC = 5 V and TA = 25°C, the SN74ABT16240ADL sustains full drive strength into 50-pF loads without timing degradation or excessive VOH/VOL shift.

Is SN74ABT16240ADL pin-compatible with SN74ABT16244ADL?

Yes-SN74ABT16240ADL and SN74ABT16244ADL share identical DL-package pinout, pin functions, and mechanical footprint. The sole functional difference is output logic polarity: SN74ABT16240ADL inverts, while SN74ABT16244ADL is non-inverting. No PCB redesign is needed when substituting between them, provided system logic accommodates the polarity change.

What is the maximum continuous output current rating for SN74ABT16240ADL?

The absolute maximum rating for continuous output current in the low state is 128 mA per SN74ABT16240ADL datasheet (page 3). However, the recommended operating condition specifies I_OL = 64 mA maximum for guaranteed VOL ≤ 0.55 V. Sustained operation above 64 mA risks exceeding thermal limits (θ_JA = 94°C/W) and violating DC specifications-so 64 mA remains the design-maximum for reliable 16-bit concurrent switching.
