Nexperia USA Inc. 74LVCH162374ADL:11

Overview

74LVCH162374ADL:11 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 interfacing in high-speed bus buffering applications such as memory address latching and data path isolation in industrial control backplanes.

For engineers reviewing the 74LVCH162374ADL:11 datasheet, 74LVCH162374ADL:11 pinout, 74LVCH162374ADL:11 application, or 74LVCH162374ADL:11 equivalent, this device delivers deterministic edge-triggered storage with sub-2 ns set-up/hold times at 3.3 V, low-noise 30 Ω output drive, and robust 5.5 V-tolerant I/O for legacy TTL and modern low-voltage logic coexistence.

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 signal, with OE controlling 3-state output drivers without affecting internal state retention.

Bus hold circuitry actively maintains logic levels on unused data inputs, eliminating external pull-ups. Integrated 30 Ω series resistors in both output stages suppress transmission-line ringing and reduce EMI in high-speed parallel buses operating up to 150 MHz at 3.3 V.

FAQ

What is the maximum clock frequency supported by the 74LVCH162374ADL:11?

The device supports up to 150 MHz at VCC = 3.3 V and ambient temperatures from -40 °C to +85 °C, and up to 120 MHz over the full -40 °C to +125 °C range. This is verified by fmax measurements in Table 7 of the datasheet under specified load and voltage conditions.

Can the 74LVCH162374ADL:11 operate with a 1.2 V supply?

Yes - it is fully specified down to 1.2 V supply voltage, with functional operation guaranteed across the entire 1.2 V to 3.6 V range. At 1.2 V, propagation delay increases to 14 ns (typical), and static parameters such as VIH/VIL scale proportionally per JEDEC JESD8-12A compliance.

How does the bus hold feature work, and what current does it source/sink?

The bus hold circuit actively maintains the last-valid logic state on each data input using weak feedback transistors. At VCC = 3.0 V, it sources ±75 μA (IBHH/IBHL), sufficient to override typical leakage but not strong enough to conflict with active drivers - eliminating need for external pull-up/down resistors.

Is the 74LVCH162374ADL:11 pin-compatible with older 74LVC16374 variants?

Yes - it uses the same TSSOP48 (SOT362-1) footprint and identical pin assignment as the 74LVC16374 series. However, it adds 30 Ω series termination and bus hold, which are inactive when unused; no layout changes are required for drop-in replacement in most existing designs.
