Product details
Overview
74LVT16374ADL,118 from Nexperia is a 3.3 V 16-bit edge-triggered D-type flip-flop with 3-state outputs, configured as two independent 8-bit sections (1CP/1OE and 2CP/2OE), operating across -40 °C to +85 °C with 2.7–3.6 V supply, 150 MHz max clock frequency, and ±64 mA output drive capability. It serves in high-speed bus interface and data latching applications in industrial control backplanes and telecom line cards.
For engineers reviewing the 74LVT16374ADL,118 datasheet, 74LVT16374ADL,118 pinout, 74LVT16374ADL,118 application, or 74LVT16374ADL,118 equivalent, key selection criteria include dual-clock domain isolation, 5.5 V-tolerant inputs for mixed-voltage system interfacing, bus-hold functionality on data inputs (LVTH variant), TSSOP48 package thermal performance, and precise set-up/hold timing (0.8 ns / 0.1 ns at 3.3 V).
Technical Context
This device implements two independent 8-bit positive-edge-triggered D-flip-flop banks, each with dedicated clock (1CP/2CP) and 3-state output enable (1OE/2OE). Inputs are overvoltage tolerant to 5.5 V, enabling direct connection to 5 V buses without level shifters.
It features BiCMOS output stages delivering +64 mA sink and –32 mA source current, supports live insertion/extraction, includes power-up 3-state and IOFF partial power-down circuitry, and meets JEDEC JESD8C (2.7–3.6 V) and JESD78 Class II Level B latch-up specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Enables stable operation across wide industrial rail tolerances; compatible with 3.3 V ±10 % systems. |
| Max Clock Frequency | 150 MHz - Supports high-throughput data capture in synchronous bus interfaces up to 300 MB/s aggregate bandwidth. |
| Propagation Delay | 1.5–5.0 ns (tPLH/tPHL) - Ensures tight timing margins in sub-10 ns cycle time designs with predictable setup/hold windows. |
| Output Drive | +64 mA / –32 mA - Drives heavy capacitive loads (e.g., 50 pF buses) without external buffers; sustains signal integrity under load. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct interfacing with legacy 5 V logic without level translation, reducing BOM count and board space. |
| Operating Temperature | –40 °C to +85 °C - Qualified for extended industrial environments including factory automation and outdoor telecom equipment. |
| Set-up/Hold Time | 0.8 ns / 0.1 ns (at 3.3 V) - Enables reliable sampling at 150 MHz with minimal timing slack; critical for DDR-adjacent capture paths. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, 1.2 mm max height - optimized for high-density PCB layouts with enhanced thermal dissipation vs. SSOP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 24 | 1OE, 2OE | Active-LOW output enables - independently disable 8-bit output groups to prevent bus contention during arbitration or power sequencing. |
| 48, 25 | 1CP, 2CP | Positive-edge clock inputs - trigger simultaneous latching of respective 8-bit input banks; support asynchronous clock domains. |
| 2–3, 5–6, 8–9, 11–12 | 1Q0–1Q7 | Group 1 3-state outputs - provide isolated 8-bit data path with high-impedance OFF-state when 1OE = HIGH. |
| 13–14, 16–17, 19–20, 22–23 | 2Q0–2Q7 | Group 2 3-state outputs - mirror Group 1 functionality with independent control; enables dual-bus or mirrored register architecture. |
| 47–37, 36–26 | 1D0–1D7, 2D0–2D7 | Data inputs - accept 5.5 V-tolerant signals; bus-hold circuitry (LVTH variant) maintains last valid state on floating inputs. |
| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight ground connections - reduce ground bounce and improve noise immunity in high-speed switching; distributed layout minimizes loop inductance. |
| 7, 18, 31, 42 | VCC | Four supply pins - lower IR drop and enhance decoupling effectiveness; supports stable core voltage under dynamic load transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit clocked sections | Independent 1CP/1OE and 2CP/2OE control enables split-bus architectures, such as separate address/data latching or redundant channel buffering. |
| 5.5 V-tolerant inputs | Eliminates need for external level translators when interfacing with 5 V microcontrollers, FPGAs, or legacy peripherals-reducing component count and signal path delay. |
| IOFF partial power-down | Prevents current backflow from powered outputs into unpowered VCC rails during hot-swap or partial system shutdown-ensuring safe live insertion. |
| Bus-hold on data inputs | Maintains valid logic state on unused or unterminated D-inputs without external pull-ups-reducing board area, cost, and risk of EMI from floating nodes. |
| Power-up 3-state | Outputs remain in high-impedance state until VCC stabilizes above 1.2 V-preventing bus conflicts during power-rail ramp-up sequences. |

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 |
|---|---|---|---|
| 74LVTH16374ADGG | Includes bus-hold circuitry on all data inputs; identical pinout and timing. | Preferred where unused inputs may float (e.g., configurable I/O headers); eliminates external pull resistors. | Select when board-level bus-hold is required and cost premium is acceptable. |
| SN74LVC16374ADGGR | TI part; 1.65–3.6 V supply range; lower drive (±24 mA); no bus-hold; different pinout (TSSOP48 but shifted pin mapping). | Suitable for low-power, single-supply 3.3 V systems where drive strength and 5 V tolerance are not required. | Choose only if redesigning PCB layout and relaxing output drive/5 V interface requirements. |
Compared with 74LVT16374ADL,118, the 74LVTH16374ADGG adds bus-hold at identical timing and drive, while SN74LVC16374ADGGR trades drive strength and voltage tolerance for lower static current and broader low-voltage compatibility-requiring layout revision and careful signal integrity revalidation.

FAQ
What is the maximum clock frequency supported by the 74LVT16374ADL,118?
The 74LVT16374ADL,118 supports a maximum clock frequency of 150 MHz at VCC = 3.3 V ± 0.3 V, as specified in Table 7 of the Nexperia datasheet Rev. 14. This value is measured under standard test conditions with CL = 50 pF and RL = 500 Ω, and reflects guaranteed performance across the full –40 °C to +85 °C temperature range.
Does the 74LVT16374ADL,118 have bus-hold functionality on its inputs?
No-the 74LVT16374ADL,118 does not include bus-hold circuitry. Bus-hold is present only in the 74LVTH16374A variant (e.g., 74LVTH16374ADGG). The LVT version relies on external pull-up/pull-down resistors for unused inputs, as confirmed in Section 2 of the datasheet where bus-hold is explicitly attributed to "74LVTH16374A only".
Can the 74LVT16374ADL,118 be used with a 5 V input bus?
Yes-the device features 5.5 V-tolerant inputs, allowing direct connection to 5 V logic signals without level-shifting circuitry. Input voltage ratings permit VI up to +7.0 V (absolute max), and recommended operation supports VI up to 5.5 V, as defined in Tables 4 and 5 of the datasheet.
What is the purpose of the IOFF circuitry in this device?
The IOFF circuitry disables output leakage current when VCC = 0 V, preventing unwanted current flow from powered I/O buses into unpowered sections of the system. This feature enables safe live insertion and extraction in hot-swap applications and ensures compliance with partial power-down requirements in modular systems.
