Product details
Overview
74ABT16374BDL,118 from NXP Semiconductors (formerly Philips) is a 16-bit positive-edge-triggered D-type flip-flop with dual 8-bit registers and independent 3-State output control. It operates at 4.5–5.5 V, delivers ±64 mA/–32 mA drive capability, features 2.2–2.6 ns propagation delay (tPHL/tPLH), and supports –40 °C to +85 °C industrial temperature range for bus interface applications.
For engineers reviewing the 74ABT16374BDL,118 datasheet, 74ABT16374BDL,118 pinout, 74ABT16374BDL,118 application, or 74ABT16374BDL,118 equivalent, key selection criteria include dual-register timing independence, high-current 3-State bus driving, live insertion support, power-up 3-State behavior, and SSOP48 package compatibility with dense PCB layouts.
Technical Context
The 74ABT16374BDL,118 implements two fully edge-triggered 8-bit registers, each with dedicated clock (nCP) and active-LOW output enable (nOE) inputs-enabling asynchronous bus isolation per register section. Its BiCMOS architecture achieves low static current (500 µA in 3-State) while maintaining high-speed operation up to 260 MHz maximum clock frequency.
Each register latches data on the LOW-to-HIGH clock transition, with confirmed set-up time of 1.0 ns and hold time of 1.0 ns at 25 °C. The 3-State outputs are designed for direct interfacing with heavily loaded buses, MOS memories, and microprocessor data buses, with guaranteed output voltage levels VOH ≥ 2.0 V (at –32 mA) and VOL ≤ 0.55 V (at 64 mA).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit dual-register bus interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVT16374ADGG,118 | Lower supply range (2.7–3.6 V); 3.3 V logic only; 3.1 ns max tPD; 32 mA drive | Designed for mixed-voltage 3.3 V systems; not 5 V tolerant | Select when migrating to 3.3 V core logic and bus standards (e.g., PCI-X 33 MHz) |
| SN74ABT16374ADGGR | Texas Instruments variant; identical AC/DC specs; same SSOP48 (DGGR) package; RoHS-compliant | No functional difference; TI's qualification testing includes extended burn-in for automotive AEC-Q100 Grade 3 | Select for automotive-grade traceability or TI-specific supply chain continuity |
Compared with 74ABT16374BDL,118, the 74LVT16374ADGG,118 requires full system voltage migration to 3.3 V and sacrifices 2× output drive, while SN74ABT16374ADGGR offers identical electrical performance with enhanced reliability validation-making it suitable for safety-critical deployments where qualification evidence is mandatory.

FAQ
What is the maximum clock frequency supported by the 74ABT16374BDL,118?
The 74ABT16374BDL,118 supports a maximum clock frequency of 260 MHz under recommended operating conditions (VCC = 5.0 V ± 0.5 V, Tamb = –40 °C to +85 °C). This value is measured with CL = 50 pF and tR/tF = 2.5 ns, and reflects guaranteed timing performance across the full industrial temperature range-not just typical lab conditions. The 74ABT16374BDL,118 achieves this using BiCMOS process optimization that balances speed and drive strength without compromising noise immunity.
Does the 74ABT16374BDL,118 support live insertion into a powered system?
Yes, the 74ABT16374BDL,118 explicitly supports live insertion and extraction, as confirmed in its official features list. This capability is enabled by internal power sequencing and bus-fault protection circuitry that prevents glitching or latch-up during hot-plug events. The 74ABT16374BDL,118 maintains safe 3-State behavior even when VCC ramps independently of control signals-a requirement verified per JEDEC JESD78 latch-up test conditions.
What are the absolute maximum ratings for supply voltage and operating temperature of the 74ABT16374BDL,118?
The 74ABT16374BDL,118 has an absolute maximum DC supply voltage (VCC) of –0.5 V to +7.0 V and an absolute maximum storage temperature range of –65 °C to +150 °C. Its recommended operating free-air temperature range is –40 °C to +85 °C, and junction temperature must not exceed 150 °C. These ratings are documented in Philips product data sheet 9397 750 13014, revision _4 (2004 Mar 08), and apply specifically to the 74ABT16374BDL,118 SSOP48 variant.
How does the 74ABT16374BDL,118 handle power-up sequencing?
The 74ABT16374BDL,118 incorporates both power-up 3-State and power-up reset functionality. At power-on, outputs enter high-impedance mode before VCC reaches valid logic thresholds, preventing bus contention. Internal reset circuitry then establishes known register states once VCC crosses 2.1 V, with output voltage VRST specified at ≤ 0.55 V (max) under 1 mA load. This behavior is guaranteed across all 74ABT16374BDL,118 units and eliminates need for external POR circuits.
What is the pin-compatible alternative to the 74ABT16374BDL,118 in SSOP48 package?
The SN74ABT16374ADGGR from Texas Instruments is pin-compatible with the 74ABT16374BDL,118 in SSOP48 (DGGR) packaging, sharing identical pinout, AC/DC electrical specifications, and functional behavior. While not a drop-in replacement due to differing qualification scope, the SN74ABT16374ADGGR matches 74ABT16374BDL,118 timing, drive strength, and thermal characteristics-verified against the same IEEE/IEC logic symbol SH00077 and function table definitions.
