Product details

Overview

74LVTN16244BBQ,518 from NXP Semiconductors is a 3.3 V, 16-bit non-inverting 3-state buffer and line driver in HXQFN60U package. It supports TTL-level input/output switching, operates from −40 °C to +85 °C, delivers ±32 mA/±64 mA output drive, and interfaces safely with 5 V systems. It serves as a bus interface component in high-speed digital backplanes and memory expansion modules.

For engineers reviewing the 74LVTN16244BBQ,518 datasheet, 74LVTN16244BBQ,518 pinout, 74LVTN16244BBQ,518 application, or 74LVTN16244BBQ,518 equivalent, this page delivers verified electrical specs, thermal-enhanced QFN pin mapping, propagation delay timing (≤3.2 ns), 3-state enable behavior, and real-world interoperability with mixed-voltage logic buses.

Technical Context

The 74LVTN16244BBQ,518 implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Its BiCMOS architecture enables TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while operating at 3.3 V VCC and tolerating 5 V inputs without damage.

All 16 outputs support true 3-state operation with power-up high-impedance, live insertion capability, and no bus loading when tied to 5 V buses. Output drive strength is asymmetric: −32 mA (HIGH) and +64 mA (LOW), optimized for driving capacitive loads on terminated transmission lines.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16244ADGGR	Lower drive (+24 mA/−24 mA); 1.65–3.6 V VCC; 56-pin TSSOP; no 5 V tolerant inputs	Suitable only for pure 3.3 V systems; cannot interface directly with 5 V buses	Select when cost and board space are prioritized over mixed-voltage interoperability and high-current drive.
74ALVCH16244DL	Higher speed (tPLH ≤ 2.3 ns typ); 2.3–3.6 V VCC; 48-pin TSSOP; 5 V tolerant inputs	Same 5 V interface capability but lower thermal performance (500 mW max) and no HXQFN option	Select when maximum speed is critical and thermal headroom is available; avoid in compact, high-power-density layouts.
