Product details
Overview
SN74ABT16374ADL from Texas Instruments is a 16-bit edge-triggered D-type flip-flop with 3-state outputs in a 48-pin SSOP (DL) package, operating from –40°C to 85°C at 4.5–5.5 V supply. It delivers ±32-mA high-drive outputs, 150-MHz max clock frequency, and supports bus-hold-free operation with high-impedance state during power up/down - used in high-speed bidirectional bus interfacing and I/O port buffering.
For engineers reviewing the SN74ABT16374ADL datasheet, SN74ABT16374ADL pinout, SN74ABT16374ADL application, or SN74ABT16374ADL equivalent, key selection criteria include 3-state output timing (tPZH/tPHZ ≤ 4.8/7.1 ns), dual 8-bit or unified 16-bit configuration flexibility, and compatibility with 5-V TTL-level systems requiring robust noise immunity and low ground bounce (<0.8 V).
Technical Context
This device implements two independent 8-bit edge-triggered D-type flip-flop sections, each with separate clock (CLK) and output-enable (OE) controls. Its EPIC-IIB BiCMOS architecture enables high-speed switching while minimizing power dissipation and ground bounce.
The distributed VCC/GND pin layout reduces high-frequency noise, and flow-through pin arrangement optimizes PCB trace routing. Internal circuitry ensures outputs enter high-impedance state when VCC is below 2.1 V, and OE remains inactive during power transitions - preserving data integrity without external sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 16-bit edge-triggered D-type flip-flop with independent 3-state control per 8-bit section |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V TTL and CMOS systems |
| Max Clock Frequency | 150 MHz - supports high-throughput data latching in backplane and memory interface applications |
| Output Drive | –32 mA IOH, +64 mA IOL - drives heavy capacitive loads without external buffers |
| Propagation Delay | tPLH/tPHL ≤ 5.4/5.6 ns - ensures tight timing margins in synchronous bus designs |
| Power-Up Behavior | Outputs enter high-impedance state when VCC < 2.1 V - prevents bus contention during power sequencing |

Pinout & Package
SN74ABT16374ADL uses a 48-pin Shrink Small-Outline Package (SSOP-DL), 300-mil body width, 0.5-mm lead pitch, with gull-wing leads and exposed thermal pad not present. Pin 1 is marked by a beveled corner or notch on the package top edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Output-enable control inputs | Active-low enables/disables respective 8-bit output banks; no effect on internal latch state |
| 1CLK, 2CLK | Clock inputs | Positive-edge triggered - samples D inputs and updates Q outputs synchronously |
| 1D1–1D8, 2D1–2D8 | Data inputs | 16 individual D inputs mapped to corresponding Q outputs on clock edge |
| 1Q1–1Q8, 2Q1–2Q8 | Tri-state outputs | High-drive outputs placed in high-Z when OE = high; otherwise drive logic levels |
| VCC, GND | Power terminals | Distributed across package (9× VCC, 9× GND) - minimizes simultaneous switching noise |
Key Features
| Feature | Design Value |
|---|---|
| High-Drive Outputs | –32 mA IOH, +64 mA IOL - eliminates need for external bus drivers in 5-V systems |
| Flow-Through Pinout | Input-to-output signal path traverses package left-to-right - simplifies layer routing and reduces crosstalk |
| Power-Up/Down High-Z | Automatic high-impedance state when VCC < 2.1 V - prevents bus conflicts during supply ramping |
| Low Ground Bounce | VOLP < 0.8 V at 5 V/25°C - maintains signal integrity under fast switching conditions |
| Latch-Up Immunity | >500 mA per JEDEC JESD-17 - ensures reliability in noisy or transient-prone environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state D-flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16374ADGGR | TSSOP-48 (DGG) package; same electrical specs, 1.2-mm max height vs. DL's 2.0-mm height | Better suited for space-constrained layouts requiring lower profile; identical timing and drive capability | Select when board height budget is <2.0 mm or automated placement favors tape-and-reel (2000/reel vs. DL's 25/tube) |
| SN74LVC16374ADL | 3.3-V only operation (1.65–3.6 V); lower drive (–24/+24 mA); 165-MHz max fCLK; different input thresholds | Designed for mixed-voltage 3.3-V systems; incompatible with 5-V buses without level translation | Choose only for 3.3-V domains where lower power and higher speed offset reduced drive strength |
Compared with SN74ABT16374ADGGR, SN74ABT16374ADL offers tube packaging for prototyping and lower-volume production, while SN74LVC16374ADL trades 5-V compatibility and drive for 3.3-V efficiency - making SN74ABT16374ADL the sole option for legacy 5-V industrial bus interfaces requiring guaranteed 64-mA sink capability.

FAQ
What is the maximum clock frequency supported by SN74ABT16374ADL?
The SN74ABT16374ADL supports a maximum clock frequency of 150 MHz under recommended operating conditions (VCC = 5 V, TA = 25°C). This value is confirmed in the timing requirements table of the official datasheet and applies across the full industrial temperature range (–40°C to 85°C), with minor derating at temperature extremes.
Does SN74ABT16374ADL have built-in power-up protection?
Yes, SN74ABT16374ADL automatically places all outputs in high-impedance state when VCC is between 0 V and 2.1 V during power-up or power-down. This behavior prevents bus contention and is intrinsic to the device's design - no external circuitry is required to achieve safe power sequencing.
Can SN74ABT16374ADL be used as two independent 8-bit registers?
Yes, SN74ABT16374ADL contains two functionally independent 8-bit sections: one controlled by 1CLK/1OE and another by 2CLK/2OE. Each section operates autonomously - allowing simultaneous latching of two 8-bit words or staggered timing control in multi-bus architectures.
What is the output drive capability of SN74ABT16374ADL?
SN74ABT16374ADL provides high-drive outputs rated at –32 mA (IOH) and +64 mA (IOL) under recommended operating conditions. These values are specified at VCC = 4.5 V and enable direct driving of heavily loaded 5-V TTL buses without external buffers or termination components.
Is SN74ABT16374ADL pin-compatible with other members of the ABT16374 family?
Yes, SN74ABT16374ADL shares identical pinout and functionality with SN74ABT16374ADGGR (TSSOP-48) and SN74ABT16374ADLR (SSOP-48 tape-and-reel variant). All variants use the same 48-pin assignment, including dual OE/CLK pairs, 16 D/Q signals, and distributed VCC/GND pins - enabling drop-in replacement across package types.
