74ALVT16821  
20-bit bus interface D-type flip-flop; positive-edge trigger;  
3-state  
Rev. 4 — 22 January 2018  
Product data sheet  
1 General description  
The 74ALVT16821 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 74ALVT16821 has two 10-bit, edge triggered registers, with each register coupled to  
a 3-state output buffer. The two sections of each register are controlled independently by  
the clock (nCP) and output enable (nOE) control gates.  
Each register is fully edge triggered. The state of each D input, one set-up time before  
the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flops Q output.  
The 3-state output buffers are designed to drive heavily loaded 3-state buses,  
MOS memories, or MOS microprocessors.  
The active low output enable (nOE) controls all ten 3-state buffers independent of the  
register operation. When nOE is LOW, the data in the register appears at the outputs.  
When nOE is HIGH, the outputs are in high-impedance OFF-state, which means they will  
neither drive nor load the bus.  
2 Features and benefits  
20-bit positive-edge triggered register  
5 V I/O compatible  
Multiple VCC and GND pins minimize switching noise  
Bus hold data inputs eliminate the need for external pull-up resistors to hold unused  
inputs  
Live insertion and extraction permitted  
Power-up reset  
Power-up 3-state  
Output capability: +64 mA and -32 mA  
Latch-up protection:  
JESD78: exceeds 500 mA  
ESD protection:  
MIL STD 883, method 3015: exceeds 2000 V  
MM: exceeds 200 V
