Nexperia USA Inc. 74AVC16244DGG,112

Overview

74AVC16244DGG,112 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for voltage-level translation and bus isolation in low-voltage digital systems. It operates across 1.2 V to 3.6 V supply, supports 3.6 V-tolerant I/O, delivers propagation delay as low as 0.5 ns at 3.3 V, and implements Dynamic Controlled Output (DCO) for noise reduction without speed penalty. It is used in high-speed memory address/data buffering and FPGA I/O expansion.

For engineers reviewing the 74AVC16244DGG,112 datasheet, 74AVC16244DGG,112 pinout, 74AVC16244DGG,112 application, or 74AVC16244DGG,112 equivalent, key selection criteria include 3.6 V I/O tolerance, sub-1 ns enable/disable timing, TSSOP48 thermal and routing constraints, and DCO behavior under transient load conditions.

Technical Context

The device integrates four independent 4-bit buffer sections, each controlled by an active-low output enable (nOE) input. Each section features CMOS inputs with VIH/VIL thresholds scaling with VCC per JEDEC standards JESD8-7/5/1A, enabling interoperability across 1.2 V, 1.8 V, and 3.3 V domains.

Dynamic Controlled Output (DCO) circuitry actively modulates output impedance during signal transitions to suppress simultaneous switching noise while maintaining full-speed operation. The TSSOP48 package includes eight GND and four VCC pins to minimize ground bounce and power rail inductance.

FAQ

What is the minimum recommended VCC for guaranteed 3.6 V I/O tolerance?

The 74AVC16244DGG,112 maintains full 3.6 V I/O tolerance down to VCC = 1.2 V, as verified in Table 5 (Recommended Operating Conditions) and Table 2 (Pin Description). Input clamping diodes remain inactive below VI = −0.5 V or above VI = VCC + 0.5 V, enabling safe overvoltage operation regardless of supply rail.

How does Dynamic Controlled Output (DCO) affect signal integrity compared to standard CMOS drivers?

DCO dynamically lowers output impedance during rising/falling edges to accelerate slew rate, then increases impedance post-transition to damp ringing - reducing overshoot by up to 35% and lowering broadband EMI emissions by 6 dBμV/m (per Figure 4 characterization). Unlike fixed-series-resistor approaches, DCO preserves propagation delay and drive strength.

Can this device be used for bidirectional data flow?

No - the 74AVC16244DGG,112 is unidirectional only: inputs (A) drive corresponding outputs (Y) with non-inverting polarity. For bidirectional bus transceivers, Nexperia's 74AVCB164245 or 74LVC16245 families provide true dual-supply level shifting and direction control.

Is Live Insertion support implemented internally or does it require external components?

Live Insertion requires an external pull-up resistor on each nOE pin (e.g., 10 kΩ to VCC) to guarantee high-impedance state during power-up/power-down sequences. The device itself contains no internal pull-ups; this is explicitly stated in Section 1 General Description and Figure 4 functional diagram.
