Product details
Overview
74ABT16273DL,118 from Nexperia is a 16-bit edge-triggered D-type flip-flop in 48-pin SSOP (SOT370-1), delivering +64 mA sink / –32 mA source output drive at 5 V, with 2.5 ns typical tPLH propagation delay and TTL-compatible input/output levels. It operates across –40°C to +85°C and supports dual 8-bit or unified 16-bit data latching in high-drive bus interface applications.
For engineers reviewing the 74ABT16273DL,118 datasheet, 74ABT16273DL,118 pinout, 74ABT16273DL,118 application, or 74ABT16273DL,118 equivalent, key selection criteria include guaranteed 150 MHz max clock frequency, master reset (active-Low) synchronization, live insertion capability, and BiCMOS-level power-speed trade-off for industrial bus buffering and register staging.
Technical Context
This device implements two independent 8-bit D-type flip-flop sections (1CP/1MR and 2CP/2MR), each with non-inverting outputs and synchronous rising-edge clock capture. All 16 Q outputs are high-drive BiCMOS, supporting direct connection to terminated transmission lines or multiple TTL loads without external buffers.
It features power-up reset behavior ensuring defined Low-state outputs at VCC ramp-up, latch-up immunity >500 mA per JEDEC JESD17, and robust ESD protection (2 kV HBM, 200 V MM). Input setup/hold times are specified down to 1.0 ns (tS) and –0.6 ns (th), enabling reliable operation at 150 MHz with minimal timing margin overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and CMOS systems while tolerating supply ripple and droop. |
| fMAX | 150 MHz - Supports high-speed data capture in memory address latching and parallel bus registration up to 150 million transitions/sec. |
| tPLH / tPHL | 2.5 ns / 2.0 ns - Enables sub-3 ns path delays from clock edge to valid output, critical for tight-tolerance synchronous logic design. |
| IOL / IOH | 64 mA / –32 mA - Drives up to 16 standard TTL loads or terminates 50 Ω lines directly, eliminating need for external drivers in bus-hold or backplane interfaces. |
| tS / th | 1.0 ns / –0.6 ns - Allows data valid as late as 0.6 ns after clock edge, simplifying PCB routing and reducing skew sensitivity in high-frequency layouts. |
| Operating Temp | –40°C to +85°C - Qualified for industrial and automotive under-hood environments where thermal cycling and extended temperature stability are required. |
| ESD Rating | 2000 V HBM - Meets MIL-STD-883 Method 3015, supporting safe handling and live insertion in automated test and field-replaceable modules. |
Pinout & Package
48-pin plastic shrink small outline package (SSOP), SOT370-1, body width 7.5 mm, 0.5 mm lead pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 | 1MR, 2MR | Active-Low asynchronous master reset - Forces all 16 Q outputs Low regardless of clock state; enables system-wide initialization. |
| 2–3, 5–6, 8–9, 11–12, 13–14, 16–17, 19–20, 22–23 | 1Q0–1Q7, 2Q0–2Q7 | Non-inverting high-drive outputs - Deliver full rail-to-rail swing with ±32 mA/±64 mA sourcing/sinking capability for bus driving. |
| 25, 48 | 1CP, 2CP | Rising-edge clock inputs - Sample D inputs on Low→High transition; separate clocks allow independent 8-bit section control. |
| 47–46, 44–43, 41–40, 38–37, 36–35, 33–32, 30–29, 27–26 | 1D0–1D7, 2D0–2D7 | Data inputs - TTL-compatible thresholds (VIL = 0.8 V, VIH = 2.0 V); accept standard 5 V logic signals without level translation. |
| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Ground reference - Eight dedicated ground pins minimize switching noise and ensure stable output impedance across all 16 bits. |
| 7, 18, 31, 42 | VCC | Positive supply - Four VCC pins reduce IR drop and improve decoupling effectiveness for high-current output switching. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process technology | Combines low static current (ICCH = 200 µA) with high-speed switching (tPLH = 2.5 ns) and strong output drive-ideal for power-constrained high-performance logic. |
| Live insertion/extraction support | Enables hot-swap capability in modular backplanes and field-upgradeable I/O cards without risk of bus contention or latch-up during plug-in. |
| Power-up reset | Guarantees all Q outputs start Low at power-on, preventing undefined bus states and eliminating need for external POR circuitry. |
| Latch-up immunity >500 mA | Complies with JEDEC JESD17 Class II, allowing safe operation in noisy industrial environments with transient voltage spikes on VCC or I/O lines. |
| TTL input/output compatibility | Direct interface with legacy 74-series, microcontroller GPIOs, and FPGA I/O banks configured for 5 V TTL standards-no level shifters required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16273DGGR | 48-pin TSSOP (SOT362-1), same electrical specs but 6.1 mm body width and 0.5 mm pitch; slightly lower thermal resistance. | Better suited for space-constrained PCBs where SSOP footprint is prohibitive; identical timing and drive performance. | Select SN74ABT16273DGGR when board area is limited and thermal dissipation margin is critical; no logic or timing redesign needed. |
| 74LVTH16273MTD | 3.3 V only (VCC = 2.7–3.6 V), LVCMOS input thresholds, 32 mA IOL, 125 MHz fMAX - not 5 V compatible. | Targeted for low-voltage mixed-signal systems; requires level translation when interfacing with 5 V buses. | Choose 74LVTH16273MTD only in pure 3.3 V domains; incompatible with 5 V TTL signaling without translators. |
Compared with SN74ABT16273DGGR, the 74ABT16273DL,118 offers identical logic function and timing but in a wider SSOP package optimized for manual assembly and thermal mass; versus 74LVTH16273MTD, it provides native 5 V operation and higher drive, avoiding translation complexity in legacy industrial designs.

FAQ
What is the maximum clock frequency supported by the 74ABT16273DL,118?
The 74ABT16273DL,118 supports a maximum clock frequency of 150 MHz over its full operating temperature range (–40°C to +85°C) and supply voltage range (4.5 V to 5.5 V). This value is guaranteed by AC characterization per the official Nexperia datasheet and reflects worst-case timing under industrial conditions-not just typical lab conditions. The 74ABT16273DL,118 achieves this using BiCMOS architecture to balance speed and drive strength without compromising reliability.
Does the 74ABT16273DL,118 support live insertion into powered systems?
Yes, the 74ABT16273DL,118 explicitly supports live insertion and extraction, as confirmed in its datasheet features list and absolute maximum ratings. Its BiCMOS input structure and controlled output turn-on behavior prevent bus contention or latch-up during hot-plug events. This makes the 74ABT16273DL,118 suitable for modular backplane systems and field-serviceable I/O cards where components may be replaced without powering down the entire system.
What is the function of pins 1 and 24 on the 74ABT16273DL,118?
Pins 1 and 24 on the 74ABT16273DL,118 are 1MR and 2MR-separate active-Low master reset inputs for the first and second 8-bit flip-flop sections. When pulled Low, each forces its corresponding eight Q outputs to Low state asynchronously, independent of clock activity. This dual-reset architecture allows selective clearing of either half of the 16-bit register, which is essential for partial system initialization in complex control logic. The 74ABT16273DL,118 uses these pins to enable flexible reset sequencing without requiring external gating logic.
Can the 74ABT16273DL,118 operate reliably at 4.5 V supply voltage?
Yes, the 74ABT16273DL,118 is fully specified and guaranteed to operate across 4.5 V to 5.5 V, with all AC and DC parameters-including 150 MHz fMAX, 2.5 ns tPLH, and 64 mA IOL-validated at VCC = 4.5 V. Its BiCMOS design maintains timing margins and drive strength even at the lower end of the supply range, making the 74ABT16273DL,118 robust against brown-out conditions in industrial power supplies where regulation may dip near 4.5 V.
Is the 74ABT16273DL,118 pin-compatible with older 74ABTH16273 variants?
No, the 74ABT16273DL,118 is not pin-compatible with the discontinued 74ABTH16273. The datasheet revision history explicitly states that references to 74ABTH16273 were deleted because that part was discontinued and superseded by the 74ABT16273 series. While both share the same pin configuration and function mapping, the 74ABTH variant used a different process and had distinct AC characteristics; therefore, direct substitution is not recommended without verifying timing closure and voltage margin in the target design. The 74ABT16273DL,118 is the current-generation replacement.
