Product Introduction
The 74LVC2244A is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. 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. 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.
Features
- Overvoltage tolerant inputs to 5.5 V
- Wide supply voltage range from 1.2 V to 3.6 V
- CMOS low-power consumption
- Direct interface with TTL levels
- Integrated 30 Ω termination resistors
- IOFF circuitry provides partial Power-down mode operation
- Complies with JEDEC standard: JESD8-7A (1.65 V to 1.95 V), JESD8-5A (2.3 V to 2.7 V), JESD8-C/JESD36 (2.7 V to 3.6 V)
- ESD protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V; CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
- Specified from -40 ℃ to +85 ℃ and -40 ℃ to +125 ℃
Applications
- - Level shifting in mixed 3.3V and 5V environments - Partial power-down applications
