Product details
Overview
74LVCH162374ADGG,1 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual 8-bit sections, 3-state outputs, 5 V input/output tolerance, integrated 30 Ω series output termination resistors, and bus hold on all data inputs. It operates from 1.2 V to 3.6 V supply and supports mixed-voltage bus interfacing in high-speed digital systems such as memory buffers and address/data latching.
For engineers reviewing the 74LVCH162374ADGG,1 datasheet, 74LVCH162374ADGG,1 pinout, 74LVCH162374ADGG,1 application, or 74LVCH162374ADGG,1 equivalent, this device is selected for its dual-octal clocked storage, robust 5 V tolerance on 3.3 V rails, low-noise output drive with built-in termination, and guaranteed operation across -40 °C to +125 °C.
Technical Context
The device implements two independent 8-bit D-type flip-flop sections, each with dedicated clock (CP) and output enable (OE) inputs. Flip-flops trigger on the LOW-to-HIGH transition of CP and retain state regardless of OE status. Outputs enter high-impedance OFF-state when OE is HIGH, without affecting internal register contents.
Bus hold circuitry maintains valid logic levels on unused data inputs, eliminating external pull-up resistors. Integrated 30 Ω series resistors in both output stages suppress line noise and reduce ringing on transmission lines - a key requirement in high-density PCB routing and backplane interfaces.

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 |
|---|---|---|---|
| SN74LVC16374ADGGR | No integrated 30 Ω termination; no bus hold; 1.65–3.6 V only; lower ESD rating (HBM 2000 V same, CDM unspecified) | Requires external termination resistors and pull-ups; unsuitable for floating-bus or high-EMI environments | Select when cost sensitivity outweighs signal integrity requirements and external components are acceptable |
| 74ALVCH162374T | Higher speed (fmax up to 200 MHz at 3.3 V); same 30 Ω termination and bus hold; identical pinout but TSSOP48 variant with different thermal pad design | Same functional replacement; optimized for higher-frequency clock domains where timing margin is critical | Select when system clock exceeds 150 MHz and thermal performance under sustained load is prioritized |
Compared with SN74LVC16374ADGGR, the 74LVCH162374ADGG,1 delivers superior signal integrity via on-die termination and eliminates BOM overhead with bus hold; versus 74ALVCH162374T, it trades peak frequency for broader voltage compatibility (1.2 V min) and identical thermal profile in SOT362-1.

FAQ
What is the minimum supply voltage required for guaranteed operation of the 74LVCH162374ADGG,1?
The device is fully specified down to 1.2 V supply voltage, with static and dynamic parameters validated across -40 °C to +125 °C at this rail. Below 1.2 V, functionality is not guaranteed per datasheet - including setup/hold times, propagation delay, and bus hold strength. Operation at 1.2 V enables compatibility with ultra-low-power microcontrollers and battery-backed systems.
Can the 74LVCH162374ADGG,1 safely drive a 5 V bus while powered from 3.3 V?
Yes - all inputs and outputs are rated for 5 V tolerance, meaning they withstand up to 5.5 V applied voltage regardless of VCC (1.2–3.6 V). When VCC = 3.3 V, outputs swing rail-to-rail (0 V to 3.3 V) but remain electrically safe when connected to 5 V pull-ups or bus lines. This eliminates level-shifting circuitry in mixed-voltage designs.
How does the bus hold feature behave when an input exceeds VCC?
When any data input voltage rises above VCC, the internal bus hold circuit automatically disables, allowing the pin to accept up to 5.5 V without damage or contention. This enables safe connection to 5 V sources while preserving bus hold functionality for inputs within the VCC range - a key enabler for hot-swap and mixed-rail debugging scenarios.
Is the 30 Ω series termination resistor located on both rising and falling edges of the output?
Yes - the 30 Ω resistor is placed in series with each output driver stage, equally attenuating both rising and falling edges. This symmetrical termination reduces ringing and overshoot on both signal transitions, improving eye diagram integrity in high-speed parallel buses without requiring external RC networks or layout tuning.
