Product details
Overview
74ABT16240ADGG,512 from Nexperia is a 16-bit inverting buffer/line driver with 3-state outputs, designed for high-speed bus interface applications in industrial and embedded systems. It features four independent output-enable inputs (1OE–4OE), ±64 mA output drive capability, TTL-compatible input/output levels, and IOFF partial power-down protection. It operates across -40 °C to +85 °C at 4.5–5.5 V supply.
For engineers reviewing the 74ABT16240ADGG,512 datasheet, 74ABT16240ADGG,512 pinout, 74ABT16240ADGG,512 application, or 74ABT16240ADGG,512 equivalent, this device supports flexible bus segmentation, hot-swap-capable backplane interfacing, and noise-sensitive logic isolation where precise voltage-level translation and low propagation delay are required.
Technical Context
The 74ABT16240ADGG,512 implements BiCMOS technology to deliver TTL-compatible switching with sub-4 ns propagation delays (tPLH/tPHL ≤ 3.7 ns) and robust output drive (+64 mA sink / -32 mA source). Its four independent 3-state control groups enable selective activation of 4-bit, 8-bit, or full 16-bit data paths without bus contention.
IOFF circuitry ensures outputs enter high-impedance state during power-down, blocking damaging backflow current even when VCC = 0 V and input/output voltages reach 4.5 V. Latch-up immunity exceeds 500 mA per JESD78B Class II Level A, and ESD protection meets HBM >2000 V and CDM >1000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across standard 5 V TTL/CMOS rail tolerances. |
| Propagation Delay | tPLH/tPHL ≤ 3.7 ns @ VCC = 5.0 V - Enables high-speed synchronous bus timing up to ~200 MHz clock domains. |
| Output Drive | +64 mA sink / -32 mA source - Drives heavy capacitive loads (e.g., long traces, multiple TTL inputs) without signal degradation. |
| IOFF Leakage | ±100 μA max @ VCC = 0 V - Prevents back-current damage during live insertion or partial system power-down. |
| Operating Temperature | -40 °C to +85 °C - Qualified for industrial-grade environments including factory automation and telecom infrastructure. |
| Input Clamping Voltage | -1.2 V to -0.9 V - Protects inputs against negative transients without external diodes. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces field failure risk in manual handling and board assembly. |
Pinout & Package
TSSOP48 package (SOT362-1), plastic thin shrink small outline, 48 leads, body width 6.1 mm, with 4 GND and 4 VCC pins to minimize switching noise and improve power integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Active-Low Output Enable | Each controls 4 outputs independently; LOW enables inversion, HIGH forces high-impedance OFF-state. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43; 41,40,38,37; 36,35,33,32; 30,29,27,26) | Data Inputs | Four 4-bit input groups; each inverted and routed to corresponding Y outputs. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6; 8,9,11,12; 13,14,16,17; 19,20,22,23) | Inverted Data Outputs | 16-bit inverting output bank with 3-state control per group; supports bus sharing and direction isolation. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground Reference | Eight dedicated ground pins reduce ground bounce and improve signal integrity in high-speed switching. |
| VCC (Pins 7,18,31,42) | Supply Voltage | Four distributed VCC pins lower supply impedance and suppress simultaneous switching noise (SSN). |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process architecture | Combines bipolar speed and CMOS low static power for <4 ns propagation with <1 mA ICC (3-state). |
| Independent 4-bit 3-state control | Four OE inputs allow granular bus partitioning-e.g., isolate memory vs. peripheral segments without global reset. |
| IOFF partial power-down | Outputs disable safely at VCC = 0 V, enabling hot-plug capability in modular backplanes and redundant power systems. |
| TTL-compatible I/O levels | Accepts 0.8 V/2.0 V VIH/VIL thresholds and delivers VOH ≥ 2.0 V / VOL ≤ 0.55 V at full load-directly interfaces legacy 5 V logic. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A-ensures reliability in noisy industrial environments with voltage transients. |
Applications
| Industrial Backplane Interface | Memory Address Buffering |
|---|---|
|
Use Scenario: Isolating CPU address/data buses from multi-slot industrial backplanes with mixed-voltage peripherals. IC Role / Device Role / Timing Role: Inverting 3-state buffer providing bidirectional bus separation and noise decoupling between master and slave slots. Use Value: Four independent OE lines allow dynamic slot enable/disable without affecting other segments; ±64 mA drive sustains signal integrity over 15 cm FR4 traces. |
Use Scenario: Driving 16-bit address lines to SRAM or Flash memory arrays in programmable logic controllers (PLCs). IC Role / Device Role / Timing Role: Inverting line driver translating microcontroller address outputs to memory inputs while supporting 3-state tristate during read cycles. Use Value: Sub-4 ns tPLH/tPHL ensures setup/hold timing margins at 25 MHz memory access; IOFF prevents leakage during memory power cycling. |
| Hot-Swappable Module Interface | Legacy System Bus Extender |
|
Use Scenario: Enabling safe insertion/removal of I/O modules in powered industrial rack systems. IC Role / Device Role / Timing Role: 3-state buffer isolating module-local logic from shared backplane bus during insertion sequence. Use Value: IOFF protection blocks backfeed current when module VCC is unpowered; HBM >2000 V withstands handling ESD events pre-connection. |
Use Scenario: Interfacing modern microcontrollers with legacy 5 V parallel peripherals (e.g., printers, displays, sensors). IC Role / Device Role / Timing Role: Level-shifting inverting buffer matching TTL input thresholds and driving legacy bus capacitance. Use Value: Direct TTL compatibility eliminates external level shifters; 6.1 mm TSSOP48 footprint fits space-constrained retrofits without PCB redesign. |
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 |
|---|---|---|---|
| SN74ABT16240DGGR (TI) | Identical logic function, pinout, and DC specs; differs in thermal resistance (θJA = 52 °C/W vs. Nexperia's 60 °C/W) and packaging (TSSOP48, same SOT362-1 footprint). | Validated in TI's automotive-qualified designs but not AEC-Q100 rated; identical industrial temp range (-40 °C to +85 °C). | Select if requiring TI's support ecosystem or existing design reuse; verify thermal margin in high-density layouts. |
| 74LVT16240ADGG,518 (Nexperia) | Lower supply range (2.7–3.6 V), reduced drive (±32 mA), faster propagation (≤2.5 ns), and no IOFF-designed for 3.3 V systems only. | Not suitable for 5 V legacy interfaces; lacks partial power-down, limiting use in hot-swap or mixed-rail systems. | Choose only for new 3.3 V designs prioritizing speed/power over 5 V compatibility or IOFF safety. |
Compared with SN74ABT16240DGGR, the 74ABT16240ADGG,512 offers superior thermal performance margin in compact layouts; versus 74LVT16240ADGG,518, it retains full 5 V interoperability and critical IOFF protection for industrial power sequencing.

FAQ
Is the 74ABT16240ADGG,512 pin-compatible with older 74ABT16240 variants?
Yes-74ABT16240ADGG,512 uses the SOT362-1 (TSSOP48) package and matches the pinout of all 74ABT16240A devices in the same package variant, including 74ABT16240ADL (discontinued SSOP48). No layout changes are needed for drop-in replacement within the same package family.
Does the IOFF feature require external biasing or configuration?
No-IOFF is fully internal and automatic. When VCC drops to 0 V, the output transistors disable regardless of input or output voltage levels (up to 4.5 V), with no external components, pull-ups, or configuration registers required. It activates inherently during power loss or sequencing.
Can this device drive a 50 pF load at 25 MHz without signal degradation?
Yes-measured tPLH/tPHL ≤ 3.7 ns at 50 pF/500 Ω load (per datasheet Table 8), yielding >135 MHz theoretical toggle rate. At 25 MHz, rise/fall times remain under 2.5 ns, preserving signal integrity with adequate setup/hold margins for synchronous interfaces.
What is the maximum continuous output current per pin during HIGH-state operation?
The absolute maximum continuous HIGH-state output current is -64 mA (source), specified at VCC = 4.5 V and VO = 2.4 V (per Table 7, Static Characteristics). Exceeding this risks parametric shift or thermal stress; sustained operation should stay within -32 mA (recommended IOH limit) for reliability.
