HEF4049B Hex inverting buffers Rev. 05 11 November 2008 Product data sheet 1. General description 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. Their guaranteed fan-out into common bipolar logic elements is shown in Table 3. It operates over a recommended V power supply range of 3 V to 15 V referenced to V DD SS (usually ground). Unused inputs must be connected to V , V , or another input. It is DD SS also suitable for use over the industrial (- 40 C to +85 C) temperature range. 2. Features n Accepts input voltages in excess of the supply voltage n Fully static operation n 5 V, 10 V, and 15 V parametric ratings n Standardized symmetrical output characteristics n Operates across the full industrial temperature range - 40 C to +85 C n Complies with JEDEC standard JESD 13-B n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V 3. Applications n LOCMOS (Local Oxidation CMOS) to DTL/TTL converter n HIGH sink current for driving two TTL loads n HIGH-to-LOW level logic conversion 4. Ordering information Table 1. Ordering information All types operate from - 40 C to +85 C.
