2.5.2.2 Type B Interface (Clock Pad)
2.5.3 Three-Volt Input Pad
MPC555
USER’S MANUAL
The pad has a capability to select the buffer for the appropriate load (45 or 90 pF). The
OE input drives the totem pole output or three-states the output.
Four subtypes are defined for the 3-V input-only pad: one with a pull-up resistor, one
with a pull-up resistor and with or without hysteresis in the receiver, one with hysteresis
