The HEF40244B is an octal non-inverting buffer with 3-state outputs. It features output stages with high current output capability suitable for driving highly capacitive loads. The 3-state outputs are controlled by the output enable inputs EOA and EOB. A HIGH on EOA or EOB causes the outputs to assume a high impedance OFF-state. The device also features hys.
• Octal bus interface
• 3-state buffers
• Fully static operation
• 5 V, 10 V, and 15 V parametric ratings
• Standardized symmetrical output characteristics
• Specified from −40 °C to +85 °C
