74ALVT162827中文资料安世数据手册PDF规格书

1 General description

The 74ALVT162827 high-performance BiCMOS device combines low static and dynamic

power dissipation with high speed and high output drive. It is designed for VCC operation

at 2.5 V or 3.3 V with I/O compatibility to 5 V.

The 74ALVT162827 20-bit buffers provide high performance bus interface buffering

for wide data/address paths or buses carrying parity. They have NOR Output Enables

(nOE0 and nOE1) for maximum control flexibility.

The 74ALVT162827 is designed with 30 Ω series resistance in both HIGH and LOW

output stages. This design reduces the line noise in applications such as memory

address drivers, clock drivers and bus receivers/transmitters.

2 Features and benefits

• Multiple VCC and GND pins minimize switching noise

• 5 V I/O compatible

• Live insertion and extraction permitted

• 3-state output buffers

• Outputs include series resistance of 30 Ω making external termination resistors

unnecessary

• Power-up 3-state

• Output capability: +12 mA and -12 mA

• Latch-up protection:

– JESD 17 exceeds 500 mA

• ESD protection:

– MIL STD 883 Method 3015: exceeds 2000 V

– MM: exceeds 200 V

• Bus hold data inputs eliminate the need for external pull-up resistors to hold unused
