Nexperia USA Inc. 74LVCH162374ADGG,5

Overview

74LVCH162374ADGG,5 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual 8-bit sections, 3-state outputs, 5 V tolerant I/O, integrated 30 Ω series output termination resistors, and bus hold on all data inputs - designed for high-speed, noise-immune bus interfacing in mixed-voltage 1.2 V to 3.6 V systems.

For engineers reviewing the 74LVCH162374ADGG,5 datasheet, 74LVCH162374ADGG,5 pinout, 74LVCH162374ADGG,5 application, or 74LVCH162374ADGG,5 equivalent, this device delivers deterministic timing (1.5 ns min t_su, 150 MHz max f_max at 3.3 V), robust level translation between 3.3 V and 5 V domains, and bus stability without external pull-ups - critical for industrial control backplanes and memory interface buffers.

Technical Context

This device implements two independent octal D-type flip-flop sections, each with dedicated clock (CP) and output enable (OE) inputs. Each section latches data on the LOW-to-HIGH transition of its CP input while meeting set-up (1.5–4.0 ns) and hold (−0.3 to 3.0 ns) time requirements across 1.2–3.6 V supply range.

Outputs enter high-impedance state when OE is HIGH, independent of clock or stored data; bus hold circuitry maintains valid logic levels on unused D inputs without external components; 30 Ω series resistors suppress ringing on transmission lines up to 150 MHz.

FAQ

Can 74LVCH162374ADGG,5 operate with V_CC = 1.2 V while driving 5 V-tolerant loads?

Yes. The device is fully specified down to V_CC = 1.2 V and maintains 5 V tolerance on all inputs and outputs across that entire supply range. Input clamping diodes and output stage design allow safe operation with VI or VO up to 5.5 V regardless of V_CC, enabling true mixed-voltage interoperability without level-shifting circuitry.

What is the function of the bus hold circuit, and how does it affect unused inputs?

The bus hold circuit actively maintains the last-valid logic state on any D input pin left floating, drawing ±75 μA at V_CC = 3.0 V. It eliminates the need for external pull-up or pull-down resistors, reduces board space and BOM count, and prevents metastability or unintended toggling due to noise on unterminated lines - critical in high-density PCB layouts.

How does the 30 Ω series termination resistor improve signal integrity?

Each output integrates a matched 30 Ω series resistor to dampen transmission line reflections on PCB traces. This reduces overshoot, undershoot, and ringing - especially on long or unterminated nets - without requiring discrete components or layout adjustments. Measured output skew remains ≤1.5 ns, preserving timing margins in high-speed parallel interfaces.

Is the 74LVCH162374ADGG,5 pin-compatible with earlier 74LVC16374 variants?

Yes - it uses identical TSSOP48 (SOT362-1) pinout and functional mapping for all 48 pins, including V_CC, GND, D/Q, CP, and OE. However, it adds bus hold and 30 Ω termination not present in base LVC versions; these features are backward-compatible and do not affect pin-level connectivity or timing behavior in existing designs.
