74ALVT162821 Description
The 74ALVT162821 is a 20-bit positive-edge triggered D-type flip-flop with 30 Ω termination resistors and 3-state outputs The device can be used as two 10-bit flip-flops or one 20-bit flip-flop.
74ALVT162821 Key Features
- Wide supply voltage range from 2.3 V to 3.6 V
- Overvoltage tolerant inputs to 5.5 V
- BiCMOS high speed and output drive
- Outputs include series resistance of 30 Ω making external termination resistors unnecessary
- No bus current loading when output is tied to 5 V bus
- Direct interface with TTL levels
- IOFF circuitry provides partial Power-down mode operation
- 20-bit positive-edge triggered register
- 5 V I/O patible
- Multiple VCC and GND pins minimize switching noise
