HEF4049B
Hex inverting buffers
The HEF4049B provides six 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.
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.
Features and benefits
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
Specified from -40 °C to +85 °C
Complies with JEDEC standard JESD 13-B
Applications
LOCMOS (Local Oxidation CMOS) to DTL/TTL converter
HIGH sink current for driving two TTL loads
HIGH-to-LOW level logic conversion
