Product details
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-designed for high-speed, noise-sensitive bus interface applications in mixed-voltage systems.
For engineers reviewing the 74LVCH162374ADL,11 datasheet, 74LVCH162374ADL,11 pinout, 74LVCH162374ADL,11 application, or 74LVCH162374ADL,11 equivalent, this device supports robust level-shifting between 1.2 V–3.6 V logic domains while maintaining signal integrity via on-die termination and low-skew propagation (≤1.5 ns at 3.3 V), making it critical for industrial control backplanes and memory expansion interfaces.
Technical Context
This device implements two independent octal D-type flip-flop sections, each with dedicated clock (CP) and output enable (OE) inputs, enabling synchronous latching and controlled bus driving. Its CMOS architecture operates across 1.2 V to 3.6 V supply, with 5 V tolerant I/Os allowing direct interfacing to legacy TTL and 5 V peripherals without external level shifters.
Each data input features active bus hold circuitry eliminating external pull-ups; outputs include 30 Ω series resistors in both high and low states to suppress line ringing and reduce EMI. The device guarantees operation from –40 °C to +125 °C and meets JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE (Pins 1, 24) | Active-low output enable | Controls 3-state output drivers independently per octal section; OE HIGH forces high-impedance, no effect on internal flip-flop state |
| 1CP, 2CP (Pins 48, 25) | Clock input | Edge-triggered on LOW-to-HIGH transition; latches corresponding D-inputs meeting setup/hold timing |
| 1D0–1D7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) | Data inputs (Section 1) | All feature bus hold circuitry; tolerate up to 5.5 V when VI > VCC, enabling 5 V-safe operation |
| 2D0–2D7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) | Data inputs (Section 2) | Identical bus hold behavior as Section 1; electrically isolated but share same VCC/GND network |
| 1Q0–1Q7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) | Outputs (Section 1) | 3-state, 30 Ω series-terminated; drive loads directly without external resistors; high-impedance when OE HIGH |
| 2Q0–2Q7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) | Outputs (Section 2) | Same termination and drive characteristics as Section 1; skew ≤1.0 ns between any two outputs switching together |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and ground bounce; supports decoupling near each functional block |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths for all I/Os and internal logic, critical for noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus-interface flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16374ADGGR | No integrated 30 Ω termination; requires external series resistors for EMI control; bus hold not implemented | Lacks on-die termination and bus hold-increases PCB complexity and risk of floating inputs in sparse layouts | Select when cost sensitivity outweighs layout simplicity and noise performance; verify external termination design |
| 74ALVCH162374T | Higher speed (fmax up to 200 MHz at 3.3 V); wider VCC range (1.65–3.6 V); identical pinout and bus hold | Better suited for high-frequency test equipment or FPGA interconnect where timing margin is critical | Choose for designs requiring >150 MHz operation or tighter setup/hold margins; otherwise 74LVCH162374ADL,11 offers optimal balance |
Compared with SN74LVC16374ADGGR, the 74LVCH162374ADL,11 reduces system-level EMI and eliminates floating-input risks via integrated termination and bus hold; versus 74ALVCH162374T, it trades minor speed for broader low-voltage operation (down to 1.2 V) and lower static power consumption.

FAQ
What is the minimum supply voltage for guaranteed operation?
The 74LVCH162374ADL,11 is fully specified down to 1.2 V supply voltage, with functional operation supported across 1.2 V to 3.6 V. At 1.2 V, propagation delay increases to 14 ns (typ), and input thresholds scale proportionally (VIH = 1.08 V min). All DC and AC parameters remain guaranteed per datasheet Table 5 and Table 6.
Can the outputs safely drive 5 V loads when VCC = 1.8 V?
Yes-the outputs are 5 V tolerant and can be pulled to up to 5.5 V when in 3-state (OE HIGH), and driven by external 5 V sources while VCC = 1.8 V. However, output HIGH voltage (VOH) will be ~1.6 V (min) at 1.8 V VCC and 2 mA load, so level translation is required if driving 5 V logic inputs.
How does the bus hold circuit behave when VCC = 0 V?
When VCC = 0 V, the bus hold circuit remains active only if an external voltage (≤5.5 V) is applied to the input pin-providing weak pull-up/pull-down to maintain logic state. Input leakage current is limited to ±10 μA (max) per pin, ensuring safe hot-plug or power sequencing scenarios.
Is the 30 Ω series termination present in both HIGH and LOW output states?
Yes-Nexperia's datasheet explicitly states "30 Ω series termination resistors are included in both high and low output stages." This symmetrical termination minimizes rise/fall time asymmetry and ensures consistent impedance matching regardless of output logic state, critical for differential signaling integrity.
