HD74HC356 8-to-1-line Data Selector/Multiplexer/Register (with 3-state outputs) REJ03D0614–0200 (Previous ADE-205-493) Rev.2.00 Jan 31, 2006 Description This data selectors/multiplexers contain full on-chip binary decoding to select one of eight data sources. The data select address is stored in transparent latches that are enabled by a low level address on pin 11, Select Control. Data on the 8 input lines is stored in a parallel input/output register which in the HD74HC356 is composed of 8 edge-triggered flipflops, clocked by a low to high transition on pin 9, clock. Both true (Y) and complementary (W) 3-state outputs are available. Features • • • • • • High Speed Operation: tpd (Clock to W, Y) = 27 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation Taping Abbreviation (Quantity) HD74HC356FPEL SOP-20 pin (JEITA) PRSP0020DD-B (FP-20DAV) FP EL (2,000 pcs/reel) HD74HC356RPEL SOP-20 pin (JEDEC) PRSP0020DC-A (FP-20DBV) RP EL (1,000 pcs/reel) Note: Please consult the sales office for the above package availability.
