Product details
Overview
74LVTH162374ZRDR from Texas Instruments is a 3.3-V ABT 16-bit edge-triggered D-type flip-flop with 3-state outputs in a 54-ball ZRD (Pb-free VFBGA) package. It features dual 8-bit operation, 22-Ω integrated output series resistors, bus-hold on all data inputs, Ioff support for hot insertion, and operates across –40°C to 85°C. It is used in bidirectional bus driving and I/O port buffering in mixed-voltage systems.
For engineers reviewing the 74LVTH162374ZRDR datasheet, 74LVTH162374ZRDR pinout, 74LVTH162374ZRDR application, or 74LVTH162374ZRDR equivalent, key selection criteria include its 3.3-V supply with 5-V tolerant inputs, 160-MHz maximum clock frequency, 12-mA output drive, 2.8-ns data setup time at 3.3 V, and Pb-free VFBGA packaging for high-density PCB layouts.
Technical Context
The 74LVTH162374ZRDR implements two independent 8-bit positive-edge-triggered D-type flip-flop banks, each with dedicated clock (1CLK/2CLK) and output-enable (1OE/2OE) controls. Its ABT (Advanced BiCMOS Technology) architecture enables TTL-level compatibility while operating from a 3.3-V supply.
It supports mixed-mode signaling: inputs tolerate up to 5.5 V regardless of VCC, and outputs drive 5-V buses directly without level shifters. Internal bus-hold circuitry eliminates external pullup/pulldown resistors on data inputs, and Ioff protection disables outputs during power-down to prevent backflow current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.7 V to 3.6 V - Enables stable operation under unregulated battery or low-noise LDO supplies. |
| Max Clock Frequency | 160 MHz - Supports high-speed data latching in memory interfaces and synchronous bus systems. |
| Output Drive | ±12 mA - Sufficient to drive standard TTL loads or stubs on terminated backplanes without external buffers. |
| Setup/Hold Time | 2.8 ns / 1.2 ns at VCC = 3.3 V - Enables reliable capture of fast data streams with minimal timing margin overhead. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to legacy 5-V logic without interface components. |
| Bus-Hold Current | ±75 µA - Actively holds floating inputs at valid logic levels, removing need for external biasing resistors. |
| Ioff Leakage | ±100 µA at VCC = 0 - Prevents damaging current flow during hot-swap or partial-power-down scenarios. |
Pinout & Package
The 74LVTH162374ZRDR is housed in a 54-ball ZRD package (Pb-free Very Thin Fine-Pitch Ball Grid Array), measuring 7.0 mm × 4.5 mm × 0.9 mm, with 0.5-mm ball pitch and bottom-side thermal pad. Pin 1 is located in quadrant Q1 per JEDEC standard tape orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Q1–1Q8, 2Q1–2Q8 | Output terminals (16 total) | 3-state CMOS outputs with integrated 22-Ω series resistors to suppress ringing and reduce EMI. |
| 1D1–1D8, 2D1–2D8 | Data inputs (16 total) | Bus-hold enabled; retain last valid logic state when un-driven, eliminating external termination. |
| 1CLK, 2CLK | Positive-edge clock inputs | Edge-sensitive latch control for respective 8-bit banks; no internal synchronization required. |
| 1OE, 2OE | Active-low output-enable inputs | Independently disable each 8-bit bank's outputs into high-impedance state without affecting internal register state. |
| VCC, GND | Power and ground connections | Distributed across package (12 VCC, 12 GND balls) to minimize simultaneous switching noise and improve signal integrity. |
| NC | No-connect balls | Internally unconnected; must be left floating or tied to GND per layout guidelines - not used for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 22-Ω output series resistors | Eliminates need for external damping resistors on PCB traces, reducing BOM count and layout area. |
| Mixed-mode I/O (3.3-V VCC, 5-V tolerant) | Interoperates directly with both 3.3-V and 5-V logic families without level translators or voltage dividers. |
| Hot-insertion support via Ioff and power-up 3-state | Outputs enter high-Z automatically during power ramp-up/down, preventing bus contention in live backplane systems. |
| Flow-through pinout architecture | Input-to-output signal path alignment simplifies layer routing and reduces trace crossovers in dense FPGA/CPU interconnects. |
| Latch-up immunity > 500 mA | Meets JESD17 requirements, ensuring robustness against transient overvoltage events in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit edge-triggered D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVTH162374DGGR | TSSOP-48 package (7.0 × 4.4 mm), leaded, 2000/reel; identical electrical specs and pinout mapping. | Better suited for prototyping, manual rework, or legacy assembly lines requiring gull-wing leads. | Select when board space allows larger footprint and hand-soldering or optical inspection is preferred. |
| SN74LVTH16374DLR | SSOP-48 package (15.4 × 7.5 mm); same logic function but lacks bus-hold and has higher ICC (5 mA vs. 0.19 mA). | Applicable where input termination is externally managed and thermal budget permits higher quiescent power. | Choose only if existing SSOP footprint reuse is mandatory and bus-hold is not required in the design. |
Compared with SN74LVTH162374DGGR and SN74LVTH16374DLR, the 74LVTH162374ZRDR offers the smallest PCB footprint, Pb-free compliance, and lowest static power - making it optimal for space-constrained, high-reliability, and RoHS-compliant production designs.

FAQ
What is the operating temperature range for the 74LVTH162374ZRDR?
The 74LVTH162374ZRDR is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in factory automation, outdoor telecom enclosures, and automotive cabin environments where thermal cycling is common. The device maintains full specification compliance-including timing, drive strength, and bus-hold functionality-across this entire range.
Does the 74LVTH162374ZRDR support hot insertion?
Yes, the 74LVTH162374ZRDR supports hot insertion via two complementary features: Ioff circuitry disables outputs when VCC = 0 V, preventing backflow current, and power-up 3-state forces outputs into high-impedance during power ramp-up. These features are fully characterized per JEDEC standards and enable safe insertion into live backplanes or powered motherboards without disrupting bus operation.
Can the 74LVTH162374ZRDR be used as a single 16-bit register or two independent 8-bit registers?
Yes, the 74LVTH162374ZRDR can operate flexibly as either one 16-bit register or two independent 8-bit registers. Its dual-clock (1CLK/2CLK) and dual-output-enable (1OE/2OE) structure allows asynchronous control of each 8-bit bank. When both clocks are tied together and both OE inputs are paralleled, it functions as a unified 16-bit edge-triggered latch.
What is the purpose of the bus-hold circuitry on the 74LVTH162374ZRDR data inputs?
The bus-hold circuitry on the 74LVTH162374ZRDR data inputs actively maintains the last valid logic state (high or low) when an input is left floating or undriven. This eliminates the need for external pullup or pulldown resistors, reducing component count, PCB area, and potential signal integrity issues caused by resistor parasitics-especially critical in high-density, high-speed layouts.
Is the 74LVTH162374ZRDR pin-compatible with other packages in the LVTH162374 family?
No, the 74LVTH162374ZRDR (54-ball ZRD VFBGA) is not pin-compatible with TSSOP (DGG) or SSOP (DL) variants due to fundamental differences in ball/grid layout, signal assignment, and power/ground distribution. While logical functionality and AC/DC specifications are identical, PCB redesign is required to migrate from DGG/DL to ZRD packaging. Always consult TI's terminal assignment tables before footprint reuse.
