8.1 Overview

This decoder/demultiplexer is designed for 1.65-V to 5.5-V V_CC operation.

The SN74LVC1G19 device is a 1-of-2 decoder/demultiplexer. This device decodes the 1-bit address on input A and places a logic low on the matching address output, Y₀ or Y₁ , when the enable (E) input signal is low.

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

SN74LVC1G19 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-power-down applications using I_off. The I_off feature ensures that damaging current will not backflow through the device when it is powered down. The SN74LVC1G19 device has isolation during power off. I_off supports live insertion, partial-power-down mode and back drive protection.
