Nexperia 74ALVT16821
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.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 Nexperia 74ALVT16821 20-bit bus interface D-type flip-flop; positive-edge trigger; 3-state 3 Ordering information Table 1. Ordering information Type number Package Temperature range 74ALVT16821DGG -40 °C to +85 °C Name
