The document provides the data sheet of Harris Semiconductor SCHS154D. The CD54HCT161 is obsolete and no longer supplied. The product features a 4-bit binary counter, asynchronous reset, synchronous counting and loading, two count enable inputs for cascading, and look-ahead carry for high-speed counting.
The document provides a comprehensive overview of the CD54HC161, CD54HCT161, CD54HC163, and CD54HCT163 devices. These are 4-bit binary counters featuring look-ahead carry logic for high-speed counting applications. The HC types utilize asynchronous reset, while the HCT types feature synchronous reset.
| Supply Voltage (HC Types) | 2V to 6V |
|---|---|
| Supply Voltage (HCT Types) | 4.5V to 5.5V |
| Operating Temperature Range | -55°C to 125°C |
The devices operate from -55°C to 125°C.
HC types require a supply voltage between 2V and 6V.
Standard outputs can drive 10 LSTTL loads over the temperature range.
