8.1 Overview

This triple Schmitt-trigger buffer is designed for 1.65-V to 5.5-V V_CC 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 (V_T+) and negative-going (V_T–) signals. This device is fully specified for partial-power-down applications using I_off. The I_off 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 V_CC Operation. All Inputs accept voltages up to 5.5 V. ±24-mA Output Drive at 3.3 V. The maximum time propagation delay (t_pd ) is 5.4 ns at 3.3 V. Low Power Consumption, 10-μA Max I_CC. Typical output ground bounce (V_OLP ) and Output V_OH Undershoot (V_OHV). This device is fully specified for partial-powerdown applications using I_off. The I_off feature ensures that damaging current will not backflow through the device when it is powered down. The SN74LVC3G17 device has isolation during power off. I_off 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).
