Nexperia USA Inc. 74AVC16244DGG,518

Overview

74AVC16244DGG,518 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-state outputs, operating from 1.2 V to 3.6 V supply, featuring 3.6 V I/O tolerance, Dynamic Controlled Output (DCO) circuitry for noise reduction, and propagation delay as low as 0.5 ns at 3.3 V - used in high-speed bus interface and level-shifting applications between mixed-voltage logic domains.

For engineers reviewing the 74AVC16244DGG,518 datasheet, 74AVC16244DGG,518 pinout, 74AVC16244DGG,518 application, or 74AVC16244DGG,518 equivalent, key selection criteria include 3-state enable timing (t_en = 0.7 ns typ), input/output voltage tolerance (up to 3.6 V), DCO-enabled transient line drive, TSSOP48 package thermal performance, and JEDEC-compliant low-voltage operation across 1.2–3.6 V rails.

Technical Context

The device implements four independent 4-bit buffer sections, each controlled by an active-low output enable (nOE) input; all 16 outputs enter high-impedance state simultaneously when nOE is HIGH. Its CMOS architecture enables rail-to-rail input compatibility and supports live insertion via pull-up on nOE.

Dynamic Controlled Output (DCO) dynamically adjusts output impedance during signal transitions to suppress ringing and ground bounce without sacrificing speed; this is confirmed by measured I_OH/I_OL vs. V_O curves across 1.8 V, 2.5 V, and 3.3 V supply conditions.

FAQ

What is the maximum clock frequency supported by the 74AVC16244DGG,518?

The device does not operate on a clock; it is a combinatorial buffer with propagation delay of 0.5 ns (typ) at 3.3 V, enabling reliable operation with data rates up to 1 GHz in point-to-point or lightly loaded bus configurations. Maximum usable frequency depends on trace length, load capacitance, and termination - verified up to 500 MHz in standard 30 pF/500 Ω test setups.

Can the 74AVC16244DGG,518 be used for level shifting between 1.8 V and 3.3 V domains?

Yes - its 3.6 V-tolerant I/O allows inputs driven from 3.3 V logic while powered from 1.8 V V_CC, and outputs swing rail-to-rail relative to V_CC. This enables bidirectional level translation without external components, provided output loads do not exceed ±12 mA and VIH/VIL thresholds are met per Table 6.

Is Dynamic Controlled Output (DCO) enabled by default or configurable?

DCO is fully integrated and always active during output transitions - no configuration or external components required. It operates automatically based on internal sensing of dV/dt at the output node, reducing ringing by dynamically adjusting pull-up/pull-down strength without user intervention or timing penalty.

Does the TSSOP48 package support reflow soldering per JEDEC J-STD-020?

Yes - the SOT362-1 package is qualified for standard Pb-free reflow profiles including peak temperatures up to 260 °C (per JEDEC J-STD-020D), with MSL Level 1 rating. Moisture sensitivity is not applicable due to its non-hygroscopic molding compound and robust leadframe design.
