Product details
Overview
74ABT16240ADL,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 buffers, each controlled by dedicated low-active output enables (1OE–4OE), and integrates IOFF circuitry for safe partial power-down operation in bus-hold or hot-swap systems.
For engineers reviewing the 74ABT16240ADL,112 datasheet, 74ABT16240ADL,112 pinout, 74ABT16240ADL,112 application, or 74ABT16240ADL,112 equivalent, key selection criteria include TTL-compatible input/output levels, sub-4 ns propagation delay, high-current sinking capability (64 mA), IOFF-enabled backflow protection, and quad-gated 3-state control for multi-segment bus isolation.
Technical Context
The device implements BiCMOS logic architecture to achieve high-speed switching (tPLH/tPHL ≤ 3.7 ns at 5.0 V) while maintaining robust output drive. Its four independent OE inputs enable granular control over 16 outputs grouped into four 4-bit banks, supporting flexible bus segmentation without external gating logic.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting reverse current to ±100 μA - critical for live insertion, hot-swap backplanes, and mixed-voltage system interoperability. Input clamping (VIK = –1.2 V) and ESD protection (HBM > 2000 V, CDM > 1000 V) ensure resilience in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and CMOS systems without level-shifting. |
| Output Drive | +64 mA sink / –32 mA source - supports driving heavy capacitive loads (e.g., >50 pF buses) and multiple TTL inputs. |
| Propagation Delay | tPLH/tPHL ≤ 3.7 ns @ 5.0 V - enables reliable operation in high-speed address/data bus applications up to ~100 MHz. |
| IOFF Leakage | ±100 μA @ VCC = 0 V - prevents damaging backflow current during partial power-down or hot-plug events. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded control, test equipment, and communications infrastructure. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level robustness. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V - guarantees clean recognition of standard TTL logic levels across full voltage/temp range. |
Pinout & Package
TSSOP48 package (SOT362-1), 6.1 mm body width, 0.5 mm lead pitch, with 8 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) | Low-active output enable | Each controls 4 outputs independently; asserted LOW enables corresponding Yn outputs, HIGH places them in high-Z. |
| 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 | 16 total inputs; each An group drives inverted outputs Yn (e.g., 1A0 → 1Y0 = NOT(1A0)). |
| 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 | 16 buffered, inverted outputs; tri-stated when respective nOE is HIGH; support bus sharing and load isolation. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight distributed ground pins reduce ground bounce and improve signal integrity in high-speed switching. |
| VCC (Pins 7,18,31,42) | Power supply | Four decoupled VCC pins lower supply impedance and suppress simultaneous switching noise across 16-bit bus. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 4-bit 3-state control | Four independent OE inputs allow selective activation of 4-output segments - eliminates need for external gating in modular bus designs. |
| IOFF partial power-down | Outputs disable safely at VCC = 0 V, limiting reverse current to ±100 μA - essential for hot-swap backplane and mixed-supply systems. |
| BiCMOS high-speed drive | Sub-4 ns propagation delay with ±64 mA sink capability enables direct interface to legacy TTL loads without external drivers. |
| Distributed power/ground | 4 VCC and 8 GND pins reduce simultaneous switching noise and improve signal integrity on dense PCB layouts. |
| TTL-compatible I/O | Inputs accept 0.8 V/2.0 V thresholds and outputs drive standard TTL fan-out - simplifies integration into heterogeneous logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16240DGGR (TI) | Same logic function, TSSOP48, but rated only to +70 °C ambient; IOFF not explicitly specified in datasheet. | Limited to commercial-temperature systems; lacks documented IOFF protection for hot-swap use cases. | Select only for cost-sensitive non-industrial applications where partial power-down is not required. |
| 74LVT16240ADL,118 (Nexperia) | Lower VCC range (2.7–3.6 V); 32 mA sink only; no IOFF; operates up to +85 °C but incompatible with 5 V buses. | Designed for 3.3 V LVT logic domains - cannot replace 74ABT16240ADL,112 in 5 V systems without level shifters. | Use only in new 3.3 V designs; not a drop-in replacement due to voltage and drive mismatch. |
Compared with SN74ABT16240DGGR and 74LVT16240ADL,118, the 74ABT16240ADL,112 uniquely combines industrial temperature range, explicit IOFF protection, and full 5 V TTL drive strength - making it the sole choice for robust 5 V hot-swap bus interfaces.

FAQ
Does 74ABT16240ADL,112 support live insertion in powered-backplane systems?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting reverse current to ±100 μA - a key feature verified in Nexperia's datasheet Section 2 and Table 9. This enables safe hot-plug operation in modular backplanes without risk of backfeed damage to adjacent powered modules.
What is the maximum capacitive load this device can drive reliably at 50 MHz?
At 50 MHz (20 ns period), the device maintains signal integrity driving up to 50 pF, as validated by its dynamic characteristics (tPLH/tPHL ≤ 3.7 ns at 5.0 V with 50 pF load per Table 7 and Fig. 5). Exceeding 50 pF increases propagation skew and may cause setup/hold violations in synchronous bus designs.
Can all 16 outputs be enabled simultaneously using a single OE signal?
No. The device has four independent low-active OE inputs (1OE–4OE), each controlling only four outputs. To enable all 16 outputs, all four OE pins must be driven LOW simultaneously. There is no internal OR/AND logic connecting the OEs - they operate strictly in parallel 4-bit groups.
Is this part qualified for automotive applications?
No. The 74ABT16240ADL,112 is specified for –40 °C to +85 °C industrial operation and is not AEC-Q100 qualified. Nexperia explicitly states in Section 14 that non-automotive qualified products are unsuitable for safety-critical or automotive use - no automotive qualification data exists for this variant.
