Product details
Overview
74ABT16273DGG,112 from Nexperia is a 16-bit edge-triggered D-type flip-flop in TSSOP48 package, featuring dual 8-bit sections with independent clock (CP) and master reset (MR) inputs, ±32 mA/±64 mA output drive, TTL-compatible I/O levels, and operation across –40°C to +85°C for industrial bus interface and data latching applications.
For engineers reviewing the 74ABT16273DGG,112 datasheet, 74ABT16273DGG,112 pinout, 74ABT16273DGG,112 application, or 74ABT16273DGG,112 equivalent, this page delivers verified functional role, timing behavior, drive capability, thermal operating range, and real-world use context - all confirmed against Nexperia's official 2004 product data sheet.
Technical Context
This BiCMOS device implements two independent 8-bit D-type flip-flop banks, each triggered on the rising edge of its dedicated clock input (1CP/2CP), with synchronous active-low master reset (1MR/2MR) that forces all Q outputs low regardless of clock state. It supports live insertion/extraction and power-up reset functionality.
Designed for high-speed 5 V TTL-level systems, it delivers 150 MHz maximum clock frequency at –40°C to +85°C, 2.5 ns typical tPLH propagation delay (CP to Q), and robust latch-up immunity (>500 mA per JEDEC JESD17), making it suitable for noise-sensitive digital control and parallel data capture where deterministic edge-triggered storage is required.

Pinout & Package
74ABT16273DGG,112 is housed in a 48-pin plastic thin shrink small outline package (TSSOP48, SOT362-1), 6.1 mm body width, 0.5 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 | 1MR, 2MR | Active-Low master reset inputs - asynchronously clear all Q outputs to Low when asserted |
| 2–3, 5–6, 8–9, 11–12, 13–14, 16–17, 19–20, 22–23 | 1Q0–1Q7, 2Q0–2Q7 | Non-inverting data outputs - provide high-drive buffered copies of stored D-input states |

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 | Same logic function, identical AC/DC specs, but packaged in SSOP48 (SOT370-1); 7.5 mm body width vs. TSSOP's 6.1 mm | Requires PCB footprint change; better thermal dissipation due to larger pad area | Select for higher-power-density layouts where thermal margin outweighs space constraints |
| 74LVT16273MTDX | Lower supply range (2.7–3.6 V), 3.3 V TTL-compatible; max fCLK = 125 MHz; ±24 mA drive | Not pin-compatible; requires level-shifting for 5 V systems; suited for mixed-voltage 3.3 V core designs | Choose only when migrating to 3.3 V infrastructure and accepting reduced speed/drive |
Compared with SN74ABT16273DGGR and 74LVT16273MTDX, the 74ABT16273DGG,112 uniquely balances 5 V TTL interoperability, 150 MHz performance, and compact TSSOP packaging - making it optimal for space-constrained industrial modules requiring direct 5 V bus interfacing without voltage translation.

FAQ
What is the maximum clock frequency supported by the 74ABT16273DGG,112 across its full operating temperature range?
The 74ABT16273DGG,112 supports a maximum clock frequency of 150 MHz from –40°C to +85°C, as specified in the AC Characteristics table of Nexperia's 2004 product data sheet. This value is guaranteed under VCC = 5.0 V ±0.5 V and CL = 50 pF loading conditions, with no derating required within the rated temperature envelope.
Does the 74ABT16273DGG,112 include power-up reset functionality, and how does it behave?
Yes, the 74ABT16273DGG,112 features built-in power-up reset. During power ramp-up, all Q outputs are held Low until VCC reaches a valid operating level and internal circuitry stabilizes - ensuring predictable initial state without external reset circuitry. This behavior is documented in the "Power-up output voltage" (VRST) parameter and functional description.
Can the 74ABT16273DGG,112 be used as two independent 8-bit flip-flops, and what pins enable this configuration?
Yes, the 74ABT16273DGG,112 is explicitly designed for dual 8-bit operation. Pins 1MR/1CP/1D0–1D7/1Q0–1Q7 form the first 8-bit section; pins 2MR/2CP/2D0–2D7/2Q0–2Q7 form the second. Each section operates independently - clock and reset signals are not shared, allowing asynchronous control of both banks.
What is the output drive capability of the 74ABT16273DGG,112, and how does it impact interface design?
The 74ABT16273DGG,112 provides ±32 mA source/sink per output (–32 mA high, +64 mA low), enabling direct drive of multiple TTL inputs or moderate gate capacitance. This eliminates need for external buffer stages in most 5 V bus applications, reducing BOM count and layout complexity while maintaining signal integrity up to 150 MHz.
Is the 74ABT16273DGG,112 pin-compatible with other packages in the same logic family, such as the SSOP variant?
No, the 74ABT16273DGG,112 (TSSOP48, SOT362-1) is not pin-compatible with the SSOP48 version (74ABT16273DL, SOT370-1), despite identical logic function and electrical specs. The TSSOP has 0.5 mm lead pitch and 6.1 mm body width; SSOP uses 0.635 mm pitch and 7.5 mm width - requiring distinct PCB footprints and assembly tooling.
