Product details
Overview
74LVCH162374ADGG:5 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual 8-bit sections, 3-state outputs, integrated 30 Ω series output termination resistors, 5 V tolerant I/O, and bus-hold inputs. It operates from 1.2 V to 3.6 V supply, supports −40 °C to +125 °C ambient, and enables mixed-voltage bus interfacing in high-speed digital systems.
For engineers reviewing the 74LVCH162374ADGG:5 datasheet, 74LVCH162374ADGG:5 pinout, 74LVCH162374ADGG:5 application, or 74LVCH162374ADGG:5 equivalent, this page delivers verified electrical parameters, TSSOP48 package layout, JEDEC-compliant voltage thresholds, dynamic timing (tpd ≤ 6.8 ns @ 3.3 V), and real-world use context for bus buffering, data latching, and level translation in industrial control and computing interfaces.
Technical Context
This device implements two independent 8-bit D-type flip-flop banks, each with dedicated clock (1CP/2CP) and output enable (1OE/2OE) inputs. Data is latched on LOW-to-HIGH transitions of CP, and outputs enter high-impedance state when OE is HIGH-without affecting internal register states.
Each data input features bus-hold circuitry eliminating external pull-ups; outputs include 30 Ω series resistors in both high and low paths to suppress line noise. Input tolerance up to 5.5 V allows direct interface with 5 V logic while operating from 1.2–3.6 V VCC.

FAQ
What is the maximum clock frequency supported by the 74LVCH162374ADGG:5?
The 74LVCH162374ADGG:5 supports up to 150 MHz maximum clock frequency at VCC = 3.0–3.6 V and −40 °C to +85 °C ambient, and 120 MHz at −40 °C to +125 °C. This is validated by tW (pulse width) and fmax specifications in the official Nexperia datasheet Rev. 4.
Does the 74LVCH162374ADGG:5 require external pull-up resistors on its data inputs?
No. The 74LVCH162374ADGG:5 includes bus-hold circuitry on all D inputs (1D0–1D7 and 2D0–2D7), which actively maintains the last valid logic state when inputs are floating - eliminating the need for external pull-up or pull-down resistors.
Can the 74LVCH162374ADGG:5 be used with a 5 V microcontroller driving its inputs while powered from 3.3 V?
Yes. The 74LVCH162374ADGG:5 has 5 V tolerant inputs, allowing it to accept 5 V logic signals while operating from a 1.2–3.6 V VCC supply - enabling direct interface with legacy 5 V MCUs without level-shifting circuitry.
What is the purpose of the 30 Ω series resistors integrated into the 74LVCH162374ADGG:5 outputs?
The 30 Ω series resistors on all Q outputs dampen signal reflections on PCB traces, reducing overshoot, undershoot, and EMI. They provide controlled impedance matching for typical FR-4 trace characteristics, improving signal integrity without requiring discrete termination components.
Is the 74LVCH162374ADGG:5 pin-compatible with other 16-bit flip-flops like the 74LVC16374?
Yes - the 74LVCH162374ADGG:5 shares identical TSSOP48 pinout (SOT362-1) and functional mapping with the 74LVC16374 family, including matching D/Q/CP/OE/GND/VCC locations. However, differences in bus-hold, termination, and voltage ratings must be verified for drop-in replacement.
