Rev. 3 0 February 0 Product data sheet General description Features and benefits 3 pplications The is a 4-to-6 line decoder/demultiplexer having four binary weighted address inputs (0 to 3), with latches, a latch enable input (LE), an enable input (E) and 6 outputs (0 to 5). When LE is HIGH, the selected output is determined by the data on n. When LE goes LOW, the last data present at n are stored in the latches and the outputs remain stable. When E is LOW, the selected output, determined by the contents of the latch, is HIGH. t E HIGH, all outputs are LOW. The enable input E does not affect the state of the latch. When the device is used as a demultiplexer, E is the data input and 0 to 3 are the address inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC. The 74HCT454 features reduced input threshold levels to allow interfacing to TTL logic levels. Input levels: For 74HC454: CMOS level For 74HCT454: TTL level 6-line demultiplexing capability Decodes 4 binary-coded inputs into 6 mutually-exclusive outputs Complies with JEDEC standard no. 7 ESD protection: HBM JESD-4F exceeds 000 V MM JESD-5- exceeds 00 V Multiple package options Specified from -40 C to +5 C and -40 C to +5 C Digital multiplexing ddress decoding Hexadecimal/BCD decoding
