Product details
Overview
74ABT16273DL,112 from Nexperia is a 16-bit edge-triggered D-type flip-flop in 48-pin SSOP (SOT370-1), featuring non-inverting high-drive outputs (+64 mA sink / –32 mA source), TTL-compatible logic levels, and dual independent clock/reset domains for 8-bit partitioning. It operates from 4.5 V to 5.5 V across –40°C to +85°C and is used in bus interface latching, data synchronization, and address/data register applications in industrial control backplanes.
For engineers reviewing the 74ABT16273DL,112 datasheet, 74ABT16273DL,112 pinout, 74ABT16273DL,112 application, or 74ABT16273DL,112 equivalent, key selection criteria include propagation delay (≤2.7 ns @ 5 V), master reset timing (tW(L) ≥ 3.3 ns), output drive capability under load, and SSOP thermal/mechanical compatibility with legacy 74ABT logic designs.
Technical Context
The 74ABT16273DL,112 implements two independent 8-bit D-type flip-flop sections (1Q0–1Q7 and 2Q0–2Q7), each with dedicated clock (1CP/2CP) and active-Low master reset (1MR/2MR). Data is latched on the rising edge of CP; MR forces Q outputs Low asynchronously.
Its BiCMOS architecture delivers low quiescent current (ICCH = 1 mA max, ICCL = 19 mA max at 5.5 V) while sustaining high-speed operation up to 150 MHz (min) over full temperature range. Input clamp voltage (VIK = –1.2 V) and ESD protection (>2000 V HBM) support live insertion in hot-swap systems.

Use Scenario: Holding slot-specific configuration addresses (e.g., DSP memory map, PHY register offsets) in modular telecom line cards with hot-swap capability. IC Role / Device Role / Timing Role: 16-bit address latch enabling deterministic access to peripheral devices; live insertion support permits field-replaceable module upgrades. Use Value: ESD rating >2000 V HBM protects against handling damage during card servicing; tW(L) ≥3.3 ns ensures robust MR pulse timing in noisy rack environments. | Use Scenario: Generating precise, synchronized 16-bit stimulus patterns for IC functional testing, where deterministic setup/hold and minimal skew are critical. IC Role / Device Role / Timing Role: Edge-triggered pattern register feeding test vectors into DUT; dual-clock domain allows independent pattern loading and output enable control. Use Value: Propagation delay variation ≤0.5 ns (tPLH–tPHL) minimizes inter-bit skew; 4 VCC pins reduce supply-induced jitter in high-frequency pattern generation. |
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 | TSSOP-48 (SOT362-1); same electrical specs but 6.1 mm body width and 0.4 mm lead pitch. | Better suited for space-constrained PCBs; requires adjusted stencil and reflow profile vs. SSOP. | Select when footprint density is prioritized over legacy SSOP compatibility. |
| 74LVCH16273APAG | 3.3 V only (1.65–3.6 V); LVCMOS I/O; lower drive (±24 mA); different pinout (no dual MR/CP). | Designed for low-voltage mixed-signal systems; incompatible with 5 V buses without level shifters. | Choose only for new 3.3 V designs requiring lower power and smaller package; not a drop-in replacement. |
Compared with SN74ABT16273DGGR, the 74ABT16273DL,112 offers wider body and larger pitch for improved manufacturability and thermal dissipation; versus 74LVCH16273APAG, it maintains 5 V interoperability and higher drive strength essential for legacy industrial backplanes.

FAQ
What is the maximum clock frequency supported by the 74ABT16273DL,112?
The 74ABT16273DL,112 supports a minimum guaranteed maximum clock frequency of 150 MHz over the full operating temperature range (–40°C to +85°C) at VCC = 5.0 V ±0.5 V. Typical operation reaches 240 MHz at 25°C. This performance stems from its BiCMOS process and ≤2.7 ns propagation delay, making the 74ABT16273DL,112 suitable for high-throughput data capture in industrial and telecom systems.
Does the 74ABT16273DL,112 support live insertion in powered systems?
Yes, the 74ABT16273DL,112 explicitly supports live insertion and extraction per its datasheet features. This capability is enabled by integrated input/output clamp diodes, >2000 V HBM ESD protection, and latch-up immunity exceeding 500 mA per JEDEC Std 17-allowing safe replacement in energized backplanes without system interruption. The 74ABT16273DL,112 is commonly deployed in modular telecom and industrial control systems requiring field-serviceability.
What are the power supply requirements for reliable operation of the 74ABT16273DL,112?
The 74ABT16273DL,112 requires a DC supply voltage between 4.5 V and 5.5 V, with recommended operation at 5.0 V ±0.5 V. Supply decoupling is critical: four VCC pins (pins 7, 18, 31, 42) and eight GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45) must be individually bypassed with 100 nF ceramic capacitors near the package. Failure to properly decouple risks timing violations or output instability, especially under heavy 64 mA sink loads. The 74ABT16273DL,112 draws ≤19 mA quiescent current when outputs are Low.
How does the master reset (MR) function work on the 74ABT16273DL,112?
The 74ABT16273DL,112 has two independent active-Low master reset inputs: 1MR (pin 1) controls outputs 1Q0–1Q7, and 2MR (pin 24) controls 2Q0–2Q7. When asserted Low, MR forces the corresponding Q outputs to Low state asynchronously-regardless of clock state or input data. A minimum pulse width of 3.3 ns is required for reliable reset. Pull-up resistors are mandatory for normal operation; the 74ABT16273DL,112 does not include internal pull-ups.
Is the 74ABT16273DL,112 pin-compatible with other 74ABT16273 variants?
Yes, the 74ABT16273DL,112 shares identical pinout and functionality with all 74ABT16273 variants including 74ABT16273DGG (TSSOP) and obsolete 74ABTH16273. Pin mapping-including dual MR/CP domains, 16 I/O pairs, and distributed VCC/GND-is standardized across packages. However, mechanical differences (SSOP vs. TSSOP) affect soldering and board layout; the 74ABT16273DL,112's SOT370-1 footprint is not interchangeable with SOT362-1 without PCB revision.
