DATA SHEET
SN74HCS125 Quadruple Buffer with 3-State Outputs and Schmitt-Trigger Inputs
1 Features
- Wide operating voltage range: 2 V to 6 V
- Schmitt-trigger inputs allow for slow or noisy input signals
- Low power consumption
- Typical ICC of 100 nA
- Typical input leakage current of ±100 nA
- ±7.8-mA output drive at 6 V
- Extended ambient temperature range: –40°C to +125°C, TA
3 Description
The SN74HCS125 contains four independent buffers with 3-state outputs and Schmitt-trigger inputs. Each buffer performs the Boolean function Y = A in positive logic. The outputs can be put into a Hi-Z state by applying a High on the OE pin.
