NC7SZ384

NC7SZ384 1-Bit Low Power Bus Switch November 1996 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 NC7SZ384M5X NC7SZ384P5X NC7SZ384L6X Package Number MA05B MAA05A MAC06A Product Code Top Mark 8Z84 Z84 C3 Package Description 5-Lead SOT23, JEDEC MO-178, 1.6mm Pb-Free 6-Lead MicroPak, 1.0mm Wide Supplied As 3k Units on Tape and Reel 5k Units on Tape and Reel 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
