Revised November 2000 NC7SZ384 TinyLogic UHS 1-Bit Low Power Bus Switch General Description Features The NC7SZ384 provides 1-bit of ultra high-speed CMOS TTL-compatible 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. ■ Space saving SOT23 or SC70 5-lead package ■ 5Ω switch connection between two ports ■ Minimal propagation delay through the switch ■ Low ICC ■ Zero bounce in flow-through mode ■ Control inputs compatible with TTL level Ordering Code: Order Package Product Code Number Number Top Mark NC7SZ384M5 MA05B 8Z84 5-Lead SOT23, JEDEC MO-178, 1.6mm NC7SZ384M5X MA05B 8Z84 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZ384P5 MAA05A Z84 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 250 Units on Tape and Reel NC7SZ384P5X MAA05A Z84 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel Package Description Logic Diagram Supplied As 250 Units on Tape and Reel Connection Diagram (Top View) Pin Description Truth Table Pin Name Description OE BO OE Bus Switch Enable L AO Connect A Bus A H HIGH-Z State Disconnect B Bus B Function TinyLogic is a trademark of Fairchild Semiconductor Corporation. © 2000 Fairchild Semiconductor Corporation DS012178 www.fairchildsemi.com NC7SZ384 TinyLogic UHS 1-Bit Low Power Bus Switch November 1996 NC7SZ384 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 3) Supply Voltage (VCC) −0.5V to +7.0V DC Switch Voltage (VS) −0.5V to +7.0V Power Supply Operating (VCC) DC Input Voltage (VIN) (Note 2) −0.5V to +7.0V Input Voltage (VIN) 0V to 5.5V Output Voltage (VOUT) 0V to 5.5V DC Input Diode Current (IIK) VIN < 0V −50 mA DC Output (IOUT) Sink Current Input Rise and Fall Time (tr, tf) 128 mA Switch Control Input DC VCC/GND Current 0 ns/V to 5 ns Switch I/O ±100 mA (ICC/IGND) 0 ns/V to DC −40°C to +85°C Operating Temperature (TA) Thermal Resistance (θJA) Storage Temperature Range −65°C to +150°C (TSTG) 4.0V to 5.5V Junction Temperature +150°C under Bias (TJ) +260°C Power Dissipation (PD) @ +85°C SOT23-5 200 mW SC70-5 150 mW 300°C/W SC70-5 425°C/W Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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. Junction Lead Temperature (TL) (Soldering, 10 Seconds) SOT23-5 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.

On resistance is determined by the lower of the voltages on the two (A or B) pins. Note 5: Per TTL driven input (VIN = 3.4V, control input only). A and B pins do not contribute to ICC. www.fairchildsemi.com 2 TA = −40°C to +85°C, Symbol Parameter tPHL, Prop Delay Bus to Bus tPLH (Note 7) tPZL, Output Enable Time Output Disable Time (V) Typ (Note 6) Min 4.5–5.5 1.0 4.0 1.0 4.5–5.5 1.0 4.0 1.0 tPHZ Capacitance CL = 50 pF, RU = RD = 500Ω Units Conditions Fig. No. Max 4.0–5.5 tPZH tPLZ, VCC 0.25 ns VI = OPEN Figures 1, 2 5.0 ns VI = 7V for tPZL 5.5 ns VI = OPEN for tPZH Figures 1, 2 5.0 ns VI = 7V for tPLZ 5.5 ns VI = OPEN for tPHZ 2.5 2.5 Figures 1, 2 (Note 8) Symbol Parameter CIN Control Pin Input Capacitance CI/O Input/Output Capacitance Typ Max Units 2 6 pF VCC = 5.0V Conditions 4.5 10 pF VCC, BE = 5.0V Note 6: All typical values are VCC = 5.0V, TA = 25°C.
