Mount it close to the bus or data source to keep trace lengths short and maintain the 10.8 ns propagation margin. The 24 mA output drive can fan out to four or five standard CMOS loads without buffering. Quiescent current of 4 µA means no thermal derating concern in dense layouts.
Yes, the CD74AC86M operates from 1.5V to 5.5V and its input logic-high threshold of 1.2V to 3.85V is compatible with 5V CMOS and TTL levels. Output drive is 24 mA at both high and low states.
The CD74AC86M belongs to the 74AC series, which offers higher output drive (24 mA versus typically 4 mA for 74HC) and faster propagation delay (10.8 ns at 5V versus roughly 20 ns for 74HC at 5V). The 74AC series also operates down to 1.5V, while 74HC typically requires 2V minimum. Both share the same quad XOR function and 14-SOIC footprint.
Key differences: the 74LVC part operates from 1.65V to 3.6V (not 5.5V), has a narrower temperature range (-40°C to 125°C versus -55°C to 125°C), and offers faster propagation delay (4.4 ns at 3.3V).
