The 74ALVC16244; 74ALVCH16244 is a 16-bit buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output enables (1OE, 2OE, 3OE and 4OE), 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.
The 74ALVCH16244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
Features and benefits
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low power consumption
MULTIBYTE™ flow-through standard pin-out architecture
Low inductance multiple VCC and GND pins for minimum noise and ground bounce
Overvoltage tolerant inputs to 5.5 V(74ALVC16244 only)
Direct interface with TTL levels
IOFF circuitry provides partial Power-down mode operation
Bushold on all data inputs(74ALVCH16244 only)
Output drive capability 50 Ω transmission lines at 85 °C
Current drive ±24 mA at 3.0 V
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Latch-up performance exceeds 2500 mA per JESD 78 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
Specified from -40 °C to +85 °C
