Product details
Overview
CLVTH16374IDGGREP from Texas Instruments is a 16-bit edge-triggered D-type flip-flop with 3-state outputs, designed for 3.3-V VCC operation while supporting 5-V TTL-level inputs and outputs. It features bus-hold on all data inputs, Ioff and power-up 3-state for hot insertion, and operates across −40°C to 85°C. It is used in bidirectional bus drivers and I/O port buffering in mixed-voltage systems.
For engineers reviewing the CLVTH16374IDGGREP datasheet, CLVTH16374IDGGREP pinout, CLVTH16374IDGGREP application, or CLVTH16374IDGGREP equivalent, key selection considerations include its 160-MHz maximum clock frequency, 2.7-V to 3.6-V supply range, 3-state output enable control, and TSSOP-48 package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent 8-bit D-type latches (or one unified 16-bit register), triggered on the positive edge of CLK. Each section has dedicated clock, output-enable (OE), and data inputs, enabling flexible partitioning in bus interface designs.
Its ABT BiCMOS process delivers low static power (0.19 mA typical ICC in disabled state) and robust noise immunity via distributed VCC/GND pins and sub-0.8-V output ground bounce (VOLP). Bus-hold circuitry eliminates external pull resistors, and Ioff protection prevents backflow during hot insertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.7 V to 3.6 V - supports unregulated battery rails down to 2.7 V without level-shifting circuitry. |
| Max Clock Frequency | 160 MHz - enables high-speed data capture in memory interfaces and synchronous bus controllers. |
| Output Drive (IOL/IOH) | 64 mA sink / −32 mA source - drives standard TTL loads directly without buffer amplification. |
| Input Voltage Range (VI) | −0.5 V to 5.5 V - accepts 5-V logic inputs while powered from 3.3-V supply, enabling mixed-mode interfacing. |
| Propagation Delay (tPLH/tPHL) | 1.9 ns to 5.2 ns - ensures tight timing margins in high-speed synchronous designs at 3.3 V. |
| Bus-Hold Current (II(hold)) | ±75 µA at VCC = 3 V - actively retains valid logic states on floating data lines, eliminating external biasing. |
| Power-Up 3-State | Active below 1.5 V VCC - prevents bus contention during power sequencing in multi-rail systems. |
Pinout & Package
TSSOP-48 package (DGG) with 0.5-mm pitch, 12.5-mm × 6.1-mm footprint, and exposed thermal pad compatible with standard reflow profiles (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Output Enable (active-low) | Independent control of each 8-bit bank's 3-state outputs; does not affect internal latch state. |
| 1CLK, 2CLK | Clock input (positive-edge sensitive) | Synchronizes data capture for respective 8-bit sections; no internal clock distribution delay between banks. |
| 1D1–1D8, 2D1–2D8 | Data inputs | All support bus-hold; tolerate 5-V inputs while VCC = 3.3 V; clamp current rated to −50 mA. |
| 1Q1–1Q8, 2Q1–2Q8 | Registered outputs | 3-state capable; VOL ≤ 0.55 V at 64 mA sink ensures TTL-compatible low-level margin. |
| VCC, GND | Power and ground | Distributed across package (12× VCC, 12× GND) to minimize simultaneous switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Hot-insertion support | Enabled by Ioff (±100 µA) and power-up 3-state - prevents damage and bus conflicts when live-plugged into backplanes. |
| Mixed-mode voltage interface | 5-V-tolerant inputs + 3.3-V VCC operation - eliminates level translators in 3.3-V/5-V system interconnects. |
| Flow-through pinout | Input-to-output signal path aligned across package width - simplifies layer routing and reduces trace length mismatch. |
| Latch-up immunity | >500 mA per JESD 17 - ensures robustness in industrial environments with transient coupling or ESD events. |
| ESD protection | 2000-V HBM, 200-V MM - exceeds JEDEC standards for handling and board assembly reliability. |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module I/O Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit latch/register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16374ADGGR | Lower drive (24 mA sink), no bus-hold, 1.65–3.6-V VCC; lacks Ioff and hot-insertion support. | Suitable only for fully 3.3-V systems with controlled I/O termination; not for mixed-voltage or hot-swap use. | Select when cost sensitivity outweighs mixed-voltage interface needs and board space allows external pull resistors. |
| 74ALVCH16374T | Higher speed (200 MHz), 2.3–3.6-V VCC, no 5-V tolerance; requires external level translation for 5-V inputs. | Used in high-frequency computing interconnects where voltage translation is already present. | Choose only if system design includes dedicated level-shifting and demands >160 MHz operation with tighter timing budgets. |
Compared with SN74LVC16374ADGGR and 74ALVCH16374T, CLVTH16374IDGGREP uniquely combines 5-V input tolerance, bus-hold, hot-insertion support, and 160-MHz performance in a single 3.3-V device-making it the only option for robust mixed-voltage I/O expansion without added components.

FAQ
What is the operating temperature range for CLVTH16374IDGGREP?
The CLVTH16374IDGGREP is specified for operation from −40°C to +85°C ambient temperature. This extended industrial range is validated per JEDEC qualification standards including temperature cycling and biased 85/85 testing, ensuring reliability in harsh environments such as factory automation and vehicle under-hood applications. The device maintains full parameter compliance-including setup/hold times and output drive-across this entire range.
Does CLVTH16374IDGGREP support hot insertion, and how is it implemented?
Yes, CLVTH16374IDGGREP supports hot insertion via two integrated features: Ioff circuitry that disables outputs when VCC = 0 V (limiting reverse current to ±100 µA), and power-up 3-state logic that forces outputs into high-impedance until VCC exceeds 1.5 V. These functions are inherent to the ABT BiCMOS process and require no external circuitry-enabling safe live replacement in backplane and modular system architectures.
Can CLVTH16374IDGGREP interface directly with 5-V logic while powered at 3.3 V?
Yes, CLVTH16374IDGGREP accepts 5-V logic-level inputs while operating from a 3.3-V VCC supply. Its input voltage range is specified to 5.5 V, and it maintains valid VIH/VIL thresholds (2.0 V/0.8 V) under 3.3-V bias. This eliminates external level shifters in mixed-voltage systems-such as connecting legacy 5-V peripherals to modern 3.3-V microcontrollers-without compromising noise margin or timing.
What is the function of bus-hold circuitry on CLVTH16374IDGGREP data inputs?
The bus-hold circuitry on CLVTH16374IDGGREP data inputs actively maintains the last-valid logic state (high or low) when inputs are floating, drawing ±75 µA to reinforce the existing level. This eliminates the need for external pullup/pulldown resistors-reducing BOM count, PCB area, and potential signal integrity issues-while ensuring deterministic behavior during power-up, reset, or tri-state conditions in unterminated buses.
Is CLVTH16374IDGGREP pin-compatible with other 16-bit flip-flops in TI's Widebus family?
CLVTH16374IDGGREP shares identical pinout and functional mapping with SN74LVTH16374 variants (e.g., CLVTH16374IDLREP in SSOP-48), including matching 1OE/2OE, 1CLK/2CLK, and D/Q assignments. However, it is not pin-compatible with non-LVTH Widebus devices like SN74LVC16374 due to differing OE polarity, drive strength, and absence of bus-hold-Ioff, and 5-V tolerance in those parts.
