SN74LVCH16652A 16-Bit Bus Transceiver and Register with 3-State Outputs
1 Features
•1 Member of the Texas Instruments Widebus™
Family
• Operates From 1.65 V to 3.6 V
• Inputs Accept Voltages to 5.5 V
• Max t_pd of 6.3 ns at 3.3 V
• Typical V_OLP (Output Ground Bounce)
< 0.8 V at V_CC = 3.3 V, T_A = 25°C
• Typical V_OHV (Output V_OH Undershoot)
> 2 V at V_CC = 3.3 V, T_A = 25°C
• Supports Mixed-Mode Signal Operation on All
Ports (5-V Input/Output Voltage With
3.3-V V_CC)
