74LVC1G126
SINGLE BUFFER GATE WITH 3-STATE OUTPUT
Description
The 74LVC1G126 is a single, non-inverting buffer/bus driver with a 3-state output. The output enters a high-impedance state when a LOW level is applied to the output enable (OE) pin. The device is designed for operation with a power supply range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed-voltage environment. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down.
Features
• Wide Supply Voltage Range from 1.65V to 5.5V • ±24mA Output Drive at 3.3V • CMOS Low Power Consumption • IOFF Supports Partial-Power-Down Mode Operation • Inputs Accept Up to 5.5V • ESD Protection Tested per JESD 22
Exceeds 200V Machine Model (A115) Exceeds 2000V Human Body Model (A114) Exceeds 1000V Charged Device Model (C101) • Latch-Up Exceeds 100mA per JESD 78, Class I • Range of Package Options • Direct Interface with TTL Levels • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) • Halogen and Antimony Free. “Green” Device (Note 3)
