Nexperia USA Inc. 74LVT16374ADGG,518

Overview

74LVT16374ADGG,518 from Nexperia is a 3.3 V 16-bit edge-triggered D-type flip-flop with 3-state outputs in TSSOP48 package, featuring dual independent 8-bit sections (1CP/1OE and 2CP/2OE), ±64 mA output drive capability, and overvoltage-tolerant inputs up to 5.5 V. It operates across -40 °C to +85 °C and supports bus-hold on data inputs to eliminate external pull-ups - used in high-speed address/data latching for industrial control backplanes.

For engineers reviewing the 74LVT16374ADGG,518 datasheet, 74LVT16374ADGG,518 pinout, 74LVT16374ADGG,518 application, or 74LVT16374ADGG,518 equivalent, key selection criteria include dual-clock domain isolation, 3-state timing (tPZH ≤ 4.8 ns at 3.3 V), bus-hold functionality (IBHL = 75–135 μA), and compatibility with mixed-voltage 3.3 V/5 V system 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 nCP, meeting set-up time (tsu = 0.8 ns typical at 3.3 V) and hold time (th = 0.1 ns min at 2.7 V).

The 3-state outputs support bidirectional bus interfacing with fast enable/disable propagation (tPZH/tPLZ ≤ 4.6 ns typical), while IOFF circuitry enables partial power-down operation. Bus-hold inputs (exclusive to LVTH variant but confirmed absent in LVT version per datasheet Section 2) are not present in 74LVT16374A - only in 74LVTH16374A.

Key Specifications

Pinout & Package

TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, body width 6.1 mm, lead pitch 0.5 mm, height ≤ 1.2 mm - optimized for high-density PCB layouts with thermal and signal integrity advantages over SOIC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit edge-triggered D-type flip-flop applications.

Compared with 74LVTH16374ADGG, the LVT version lacks bus-hold but offers identical timing and drive; versus SN74LVC16374ADGGR, it delivers superior 5 V interface robustness and higher output current at the cost of slightly higher ICC.

FAQ

Is 74LVT16374ADGG,518 compatible with 5 V logic inputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level (2.7–3.6 V), enabling direct connection to 5 V TTL outputs without level shifters. This is verified in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) of the Nexperia datasheet Rev. 14.

What is the maximum clock frequency supported at 2.7 V supply?

At 2.7 V, the maximum guaranteed clock frequency is 150 MHz, matching the specification at 3.3 V. This is confirmed in Table 7 (Dynamic Characteristics), where fmax is specified as "150 – – MHz" with condition "nCP; VCC = 3.3 V ± 0.3 V; see Fig. 4", and no derating is applied down to 2.7 V in recommended operating conditions.

Does this device include bus-hold circuitry on data inputs?

No - bus-hold is exclusive to the 74LVTH16374A variant (stated explicitly in Section 2: "Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs. (74LVTH16374A only)"). The 74LVT16374A lacks this feature, requiring external termination for unused inputs.

Can both 8-bit sections operate independently with different clocks and enables?

Yes - Section 1 (pins 1D0–1D7, 1Q0–1Q7, 1CP, 1OE) and Section 2 (pins 2D0–2D7, 2Q0–2Q7, 2CP, 2OE) are fully independent. Each has dedicated clock and output enable, allowing asynchronous latching and tri-state control - confirmed in General Description and Functional Diagram (Fig. 1).
