Features of High-Speed CMOS Logic
Hitachi's HS-CMOS logicsthe HD74HC seriesand the HCT series based on the EIA/JEDEC specification. Their specification are shown in the Maximum Ratings and the Electrical Characteristics Tables. The HS-CMOS has the characteristics of both standard CMOS logic series and LS-TTL series. The features of this logic are: · High-Speed equivalent to the LS-TTL's · Capable of driving 10LS-TTL loads (Capable of driving 15LS-TTL loads in bus drivers) · Maximum input current of ± 1 µA at 6 V power supply · Wide supply voltage range: HC series 2 to 6 V HCT series 4.5 to 5.5 V · Wide noise margin · VCC assurance of Electrical Characteristics at 2.0, 4.5 and 6.0 V · Low Static Power Consumption 1/2 of EIA/JEDEC
Type Name of High-Speed CMOS Logic
The JEDEC has divided the HS-CMOS's into two types: HC and HCT. The HC type has the CMOS logic level for inputs and outputs with buffers. The HCT type has the TTL logic level for inputs and the outputs have buffers. The industry-standarized maximum ratings and recommended operating range are shown below. Limits for the static characteristics are shown below (right): Table 1 is in the industry-standard and Table 2 is the Hitachi specifications. The Hitachi specifications is used throughout this data book. Additional specification are shown in the individual data sheets. Switching characteristics are specified under the following conditions: · Input pulse voltage: + VCC · Load capacitance: 50 pF · Input pulse rise/fall time: 6 ns Switching times measured from 50% point of input voltage to 50% point of output voltage · Three different supply voltages: 2.0, 4.5 and 6.0 V
