74LVC1G34
Single buffer
Rev. 9 — 18 January 2022
Product data sheet
1. General description
The 74LVC1G34 is a single buffer. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
2. Features and benefits
• Wide supply voltage range from 1.65 V to 5.5 V • Overvoltage tolerant inputs to 5.5 V • High noise immunity • ±24 mA output drive (VCC = 3.0 V) • CMOS low power dissipation • Latch-up performance exceeds 250 mA • IOFF circuitry provides partial Power-down mode operation • Direct interface with TTL levels • Complies with JEDEC standard:
• JESD8-7 (1.65 V to 1.95 V) • JESD8-5 (2.3 V to 2.7 V) • JESD8C (2.7 V to 3.6 V) • JESD36 (4.5 V to 5.5 V) • ESD protection: • HBM: ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2000 V • MM: JESD22-A115-A exceeds 200 V • Multiple package options • Specified from -40 °C to +85 °C and -40 °C to +125 °C
