74ALVT162821
20-bit bus interface D-type flip-flop; positive?-?edge trigger with 30 Ohm termination resistors; 3?-?state
The 74ALVT162821 is a 20??-??bit positive?-?edge triggered D?-?type flip?-?flop with 30 ? termination resistors and 3?-?state outputs
The device can be used as two 10?-?bit flip?-?flops or one 20?-?bit flip?-?flop. The device features two clocks (1CP and 2CP) and two output enables (1OE and 2OE), each controlling 10?-?bits. The flip?-?flops will store the state of their individual D?-?inputs that meet the set?-?up and hold time requirements on the LOW?-?to?-?HIGH clock (nCP) transition. A HIGH on nOE causes the outputs to assume a high?-?impedance OFF?-?state. Operation of the nOE input does not affect the state of the flip?-?flops. Bus hold data inputs eliminate the need for external pull?-?up resistors to define unused inputs
Features and benefits
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 ? 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 compatible
Multiple VCC and GND pins minimize switching noise
Bus hold on data inputs
Live insertion and extraction permitted
Power-up reset
Power-up 3-state
Output capability: +12 mA and -12 mA
