Product details

Overview

74LVT16240ADL,118 from Nexperia is a 3.3 V 16-bit inverting 3-state buffer/driver in TSSOP48 package, designed for high-speed bus interface applications with ±64 mA/–32 mA output drive capability, TTL-compatible I/O levels, and bus-hold inputs eliminating external pull-ups. It operates across –40 °C to +85 °C and supports mixed-voltage interfacing between 3.3 V logic and 5 V buses.

For engineers reviewing the 74LVT16240ADL,118 datasheet, 74LVT16240ADL,118 pinout, 74LVT16240ADL,118 application, or 74LVT16240ADL,118 equivalent, this device is selected for high-drive, low-skew bus buffering in industrial control backplanes, memory address/data latching, FPGA I/O expansion, and hot-pluggable peripheral interfaces requiring live insertion support and power-up 3-state behavior.

Technical Context

The 74LVT16240ADL,118 implements four independent 4-bit inverting buffer sections, each controlled by a dedicated active-low output enable (1OE–4OE), enabling granular bus segment control. Its BiCMOS architecture delivers TTL-level input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while operating from a 3.3 V supply.

It features bus-hold circuitry on all 16 data inputs (IBHL = 75–135 μA at 3 V), ensuring stable logic states on floating inputs without external resistors. Propagation delays are tightly specified: tPLH/tPHL ≤ 3.2 ns at VCC = 3.3 V, and enable/disable times (tPZH/tPLZ) ≤ 4.5 ns, supporting >200 MHz bus operation under load.

FAQ

Can 74LVT16240ADL,118 safely interface with 5 V logic inputs while powered at 3.3 V?

Yes. The device accepts input voltages up to 5.5 V regardless of VCC level, per Table 5 (VI max = 5.5 V). Its TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) ensure reliable recognition of 5 V logic levels without damage or level-shifting circuitry.

What is the purpose of the eight GND pins in the TSSOP48 package?

The eight GND pins provide low-inductance, distributed return paths for high-current switching outputs (up to 64 mA per output). This minimizes ground bounce, reduces simultaneous switching noise, and improves signal integrity on wide parallel buses operating above 20 MHz.

How does bus-hold functionality eliminate external pull-up resistors?

Bus-hold circuitry actively maintains the last-valid logic state on each input using internal feedback transistors. With IBHL = 75–135 μA at 3 V, it supplies sufficient current to override typical leakage, preventing floating inputs without adding 16 external resistors or increasing board space and BOM cost.

Is 74LVT16240ADL,118 qualified for hot-plug operation?

Yes. It supports live insertion/extraction per datasheet Section 2, featuring power-up 3-state (outputs remain high-Z until VCC stabilizes) and Ioff protection (< ±100 μA at VCC = 0 V), preventing backfeeding and bus contention during partial connector engagement.
