HCMOS

• DC supply voltage
• DC input voltage range
• DC output voltage range
• input rise and fall times
• output rise and fall times

Variations

• HCT stands for high-speed CMOS with transistor–transistor logic voltages. These devices are similar to the HCMOS types except they will operate at standard TTL power supply voltages and logic input levels. This allows for direct pin-to-pin compatible CMOS replacements to reduce power consumption without loss of speed.
• HCU stands for high-speed CMOS un-buffered. This type of CMOS contains no buffer and is ideal for crystals and other ceramic oscillators needing linearity.
• VHCMOS, or AHC, stands for very high-speed CMOS or advanced high-speed CMOS. Typical propagation delay time is between 3 ns and 4 ns. The speed is similar to Bipolar Schottky transistor TTL.
• AHCT stands for advanced high-speed CMOS with TTL inputs. Typical propagation delay time is between 5 ns and 6 ns.
