74ALVC244
Octal buffer/line driver; 3-state
The 74ALVC244 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.
Schmitt trigger action on all inputs makes the device tolerant of slow 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.
Features and benefits
Wide supply voltage range from 1.65 V to 3.6 V
CMOS low power dissipation
Overvoltage tolerant inputs to 3.6 V
Direct interface with TTL levels
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD78 Class II.A
Complies with JEDEC standards:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8C/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
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
