8 Detailed Description

8.1 Overview

This triple Schmitt-trigger buffer is designed for 1.65-V to 5.5-V VCC operation. The SN74LVC3G17 device

contains three buffers and performs the Boolean function Y = A. The device functions as three independent

buffers but, because of Schmitt action, it may have different input threshold levels for positive-going (VT+) and

negative-going (VT–) signals. This device is fully specified for partial-power-down applications using Ioff. The Ioff

circuitry disables the outputs, preventing damaging current backflow through the device when it is powered

down. NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the

package.

8.3 Feature Description

SN74LVC3G17 is available in NanoFree package. NanoFree is a major breakthrough in IC packaging concepts,

it is a bare die package developed for applications that require the smallest possible package. The device

supports 5-V VCC Operation. All Inputs accept voltages up to 5.5 V. ±24-mA Output Drive at 3.3 V. The maximum

time propagation delay (tpd ) is 5.4 ns at 3.3 V. Low Power Consumption, 10-μA Max ICC. Typical output ground

bounce (VOLP ) and Output VOH Undershoot (VOHV). This device is fully specified for partial-powerdown

applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it

is powered down. The SN74LVC3G17 device has isolation during power off. Ioff supports live insertion, partial-

power-down mode and back drive protection. The device is latch-up resistant with 100 mA exceeding the JESD

78 standard, class II, providing protection from destruction due to latch-up. This device is protected against

electrostatic discharge. It is tested per JESD 22 using 2000-V human-body model (A114-B), 200-V machine

model (A115-A), and 1000-V charged-device model (C101).
