Product details

4-bit inverting buffer — bus interface workhorse

The Texas Instruments SN74LVT162240DGG is a 4-element, 4-bit-per-element inverting buffer with 3-state outputs from the 74LVT logic family. It sits between a bus master and a shared data or address bus, providing signal buffering and isolation. Each of the four elements handles four bits independently, and the 3-state outputs let multiple drivers share the same bus lines without contention. The part operates from a 2.7V to 3.6V supply, matching 3.3V logic rails common in telecom, industrial control, and networking equipment.

12 mA drive — enough for a loaded backplane?

The output drive is rated 12 mA source and 12 mA sink per pin.

It is not qualified to AEC-Q100, so for under-hood automotive use you would look at the 74LVC or 74AHCT automotive-grade variants.

Package: 48-TFSOP / 48-TSSOP

Supplied in a 48-lead TFSOP (0.240", 6.10 mm width) body, also referred to as TSSOP.

Active lifecycle — no end-of-life concern

The part is ROHS3 compliant.

Frequently asked questions

What voltage does SN74LVT162240DGG use?

The supply voltage range is 2.7V to 3.6V, making it a native 3.3V logic part. It is not 5V-tolerant on the inputs or outputs.

What is the difference between 74LVT and 74LVC?

74LVT is a BiCMOS family optimised for higher output drive (typically 12–24 mA) and lower propagation delay at 3.3V, while 74LVC is a pure CMOS family with wider supply range (1.65V to 5.5V) and lower quiescent current. 74LVC parts are more common for battery-powered or mixed-voltage designs; 74LVT is preferred for heavily loaded 3.3V buses where drive strength matters more than standby power.

Is SN74LVT162240DGG a direct replacement for SN74LVTH162240?

The SN74LVTH162240 is a similar 16-bit inverting buffer with 3-state outputs, but it belongs to the 74LVTH family which includes bus-hold circuitry on the inputs. The SN74LVT162240DGG does not have bus-hold. If your design relies on bus-hold to maintain a valid logic level when the bus is undriven, the LVTH variant is the correct part. Otherwise, the LVTH and LVT parts are functionally interchangeable in most bus-buffer applications.
