ABSTRACT:
A TTL to CMOS buffer circuit includes a relatively high-speed first inverter path and a second relatively low-speed inverter path connected to the first path and effective to control the operation of the first path inverter so that short-duration positive- or negative-going noise pulses of amplitude up to 2.4 volts do not incorrectly affect the output level.
