The CMOS cell is basically composed of two complementary transistors (a P-channel and an N-chan-
nel), and, in the steady state, only one transistor is turned-on. The active P-channel transistor sources
current when the output is a logic high and presents a high impedance when the output is a logic low.
Thus the overall result is extremely low power consumption because there is no power loss through the
active P-channel transistor. Also since only once transistor is determined by leakage currents.
Because the basic CMOS cell is composed of two complementary transistors, a parasitic semiconductor
controlled rectifier (SCR) formed and may be triggered when an input exceeds the supply voltage. The
SCR that is formed by this high input causes the device to become “latched” in a mode that may result in
excessive current drain and eventual destruction of the device. Although the device is implemented with
input protection diodes, care should be exercised to ensure that the maximum input voltages specifica-
tion is not exceeded from voltage transients; others may require no additional circuitry.
The TS68C429A doesn’t satisfy totally the input/output drive requirements of TTL logic devices, see
