Product details
Overview
74ABT16240ADGG,112 from Nexperia is a 16-bit inverting buffer/line driver with 3-state outputs in TSSOP48 package, operating from 4.5 V to 5.5 V supply, delivering ±64 mA/–32 mA drive capability, and specified for –40 °C to +85 °C industrial temperature range. It functions as four independent 4-bit inverting buffers, each controlled by dedicated active-low output enables (1OE–4OE), and supports partial power-down via IOFF circuitry for backflow current prevention.
For engineers reviewing the 74ABT16240ADGG,112 datasheet, 74ABT16240ADGG,112 pinout, 74ABT16240ADGG,112 application, or 74ABT16240ADGG,112 equivalent, this device is selected for high-drive, noise-immune bus interfacing in legacy TTL-compatible systems requiring precise timing control, hot-swap capability, and robust ESD protection (HBM >2000 V, CDM >1000 V).
Technical Context
The 74ABT16240ADGG,112 implements BiCMOS logic architecture to achieve sub-4 ns propagation delays (tPLH/tPHL ≤ 3.7 ns) while maintaining TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and 5 V supply compatibility. Its four independent 3-state output groups enable selective bus isolation without affecting other channels.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage to ±100 μA and preventing destructive backflow current during partial system power-down. The device features eight ground pins and four VCC pins to minimize switching noise and improve signal integrity across all 16 buffered paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across standard 5 V rail tolerances and brown-out resilience. |
| Output Drive | +64 mA / –32 mA - Supports heavy capacitive loads and fan-out to multiple TTL inputs without external buffering. |
| Propagation Delay | tPLH/tPHL ≤ 3.7 ns @ VCC = 5.0 V - Enables reliable operation in high-speed address/data bus applications up to ~200 MHz. |
| IOFF Leakage | ±100 μA @ VCC = 0 V - Guarantees safe hot-insertion and prevents bus contention during live board replacement. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets industrial-grade handling requirements without additional protection circuitry. |
| Operating Temperature | –40 °C to +85 °C - Qualified for deployment in industrial control, telecom infrastructure, and embedded computing environments. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Ensures direct interoperability with standard 5 V TTL logic families without level-shifting. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, with 8 GND and 4 VCC pins for low-noise power distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Active-low output enable | Individually controls 4-output groups; HIGH forces corresponding Yn outputs into high-impedance 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) | Inverting data inputs | Each group of four inputs drives inverted outputs on corresponding Yn pins (e.g., 1A0 → 1Y0). |
| 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) | Inverting 3-state outputs | Deliver inverted logic states with ±64 mA/–32 mA drive; enter high-Z when respective nOE = HIGH. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Distributed supply connections reduce IR drop and switching noise across 16-bit bus path. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths for all output drivers and internal logic. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process technology | Enables <4 ns propagation delay while sustaining 64 mA sink current at 5 V - critical for high-fanout bus driving. |
| IOFF partial power-down | Prevents damaging backflow current during VCC ramp-down or hot-swap; validated to JESD78B Class II latch-up >500 mA. |
| Multiple VCC/GND distribution | Four VCC and eight GND pins suppress simultaneous switching noise (SSN), improving signal integrity on dense PCB layouts. |
| TTL-compatible I/O levels | Direct interface with legacy 5 V TTL systems without level shifters - VIH min = 2.0 V, VOL max = 0.55 V @ 64 mA. |
| Live insertion/extraction support | IOFF + ESD hardening (HBM >2000 V) allows safe field-replacement in powered-backplane systems. |

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 | Same logic function, identical pinout, but TI version uses SSOP-48 (SOT370-1) with 0.635 mm pitch vs. Nexperia's 0.5 mm TSSOP. | Requires PCB footprint redesign; thermal resistance differs due to package geometry - not drop-in replaceable. | Select only if SSOP-48 is already standardized in your assembly process and thermal derating is verified. |
| 74LVT16240ADGG,112 | Lower voltage operation (2.7–3.6 V), reduced drive (±32 mA), faster propagation (~2.5 ns), no IOFF circuitry. | Not suitable for 5 V TTL systems or partial power-down scenarios; requires separate level translation for legacy interfaces. | Choose only for new 3.3 V designs where power efficiency and speed outweigh 5 V compatibility and IOFF safety. |
Compared with SN74ABT16240DGGR, the 74ABT16240ADGG,112 offers finer-pitch TSSOP packaging and guaranteed IOFF for hot-swap; versus 74LVT16240ADGG,112, it provides full 5 V TTL interoperability and higher drive strength essential for legacy bus loading.

FAQ
What is the maximum clock frequency supported by the 74ABT16240ADGG,112?
The device does not operate as a clocked sequential element; it is a combinational buffer. Its 3.7 ns maximum propagation delay (tPLH/tPHL) supports reliable data transfer on buses with signal periods ≥7.4 ns - effectively enabling use in systems with data rates up to ~135 MHz for single-bit edges, assuming proper layout and load management.
Can the 74ABT16240ADGG,112 be used with 3.3 V logic inputs?
No - its input thresholds are designed for 5 V TTL: VIH minimum is 2.0 V, but VIL maximum is 0.8 V. A 3.3 V logic HIGH may not exceed VIH reliably across voltage and temperature extremes, risking undefined output states. Use only with 5 V-compatible sources or add level translation.
Does the 74ABT16240ADGG,112 require external pull-up or pull-down resistors on its outputs?
No - outputs are actively driven HIGH or LOW when enabled, and enter true high-impedance (not floating) when disabled. External resistors are unnecessary unless specific bus-termination or fail-safe biasing is required by the system architecture.
How does the IOFF feature behave during power sequencing?
When VCC drops below ~0.8 V, IOFF circuitry automatically disables all outputs, limiting OFF-state leakage to ±100 μA and blocking reverse current flow from powered bus lines into the unpowered IC - protecting both the device and upstream drivers during asymmetric power-down sequences.
