HEF4050B
Datasheet
General description
The HEF4050B provides six non-inverting buffers with high current output capability suitable for driving TTL or high capacitive loads. Since input voltages in excess of the buffers' supply voltage are permitted, the buffers may also be used to convert logic levels of up to 15 V to standard TTL levels. Their guaranteed fan-out into common bipolar logic elements is shown in Table 3.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the industrial (-40 Cel to +85 Cel) temperature range.
Features
- Accepts input voltages in excess of the supply voltage
- Fully static operation
- 5 V, 10 V, and 15 V parametric ratings
- Standardized symmetrical output characteristics
- Operates across the full industrial temperature range -40 Cel to +85 Cel
- Complies with JEDEC standard JESD 13-B
- ESD protection:
- HBM JESD22-A114E exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
