74ALVCH162827
FEATURES
• Complies with JEDEC standard no. 8-1A.
DESCRIPTION
The 74ALVCH162827 high-performance CMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
• CMOS low power consumption
• Direct interface with TTL levels
• Current drive ± 12 mA at 3.0 V
The 74ALVCH162827 20-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NAND Output Enables (nOE1, nOE2) for
maximum control flexibility.
TM
• MULTIBYTE flow-through standard pin-out architecture
The 74ALVCH162827 is designed with 30Ω series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.
• Low inductance multiple V and GND pins for minimum noise
CC
and ground bounce
• Integrated 30 W termination resistors
To ensure the high impedance state during power up or power
down, OE should be tied to V through a pullup resistor; the
CC
minimum value of the resistor is determined by the
current-sinking/current-sourcing capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.
