Revised December 2005 NC7SZ384 1-Bit Low Power Bus Switch General Description The NC7SZ384 provides 1-bit of ultra high-speed CMOS TTLcompatible bus switch. The low On Resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 1-bit switch with a bus enable (OE) signal. When OE is LOW, the switch is on and Port A is connected to Port B. When OE is HIGH, the switch is open and a high-impedance state exists between the two ports. Features O Space saving SOT23 or SC70 5-lead package O Ultra small MicroPak¥ leadless package O 5: switch connection between two ports O Minimal propagation delay through the switch O Low ICC O Zero bounce in flow-through mode O Control inputs compatible with TTL level Ordering Code: Order Number Package Number Product Code Top Mark NC7SZ384M5X MA05B 8Z84 5-Lead SOT23, JEDEC MO-178, 1.6mm NC7SZ384P5X MAA05A Z84 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZ384L6X MAC06A C3 Pb-Free 6-Lead MicroPak, 1.0mm Wide Package Description Supplied As 3k Units on Tape and Reel 5k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.
