FAST CMOS 8-INPUT MULTIPLEXER IDT54/74FCT151T/AT/CT Integrated Device Technology, Inc. FEATURES: DESCRIPTION: • • • • • The IDT54/74FCT151T/AT/CT are high-speed 8-input multiplexers built using an advanced dual metal CMOS technology. They select one bit of data from up to eight sources under the control of three select inputs. Both assertion and negation outputs are provided. The IDT54/74FCT151T/AT/CT has a common Active-LOW enable (E) input. When E is LOW, data from one of eight inputs is routed to the complementary outputs according to the 3-bit code applied to the Select (S0-S2) inputs. A common application of the ‘FCT151 is data routing from one of eight sources. • • • • • • Std., A, and C speed grades Low input and output leakage ≤1µA (max.) Extended commercial range of –40°C to +85°C CMOS power levels True TTL input and output compatibility – VOH = 3.3V (typ.) – VOL = 0.3V (typ.) High drive outputs (-15mA IOH, 48mA IOL) Power off disable outputs permit “live insertion” Meets or exceeds JEDEC standard 18 specifications Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Available in DIP, SOIC, CERPACK and LCC packages FUNCTIONAL BLOCK DIAGRAM I7 I6 I5 Z I4 Z I3 I2 I1 I0 S2 S1 S0 E 2635 drw 01 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
