Revised August 2004 NC7ST32 TinyLogic HST 2-Input OR Gate General Description Features The NC7ST32 is a single 2-Input high performance CMOS OR Gate, with TTL-compatible inputs. Advanced Silicon Gate CMOS fabrication assures high speed and low power circuit operation. ESD protection diodes inherently guard both inputs and output with respect to the VCC and GND rails. High gain circuitry offers high noise immunity and reduced sensitivity to input edge rate. The TTL-compatible inputs facilitate TTL to NMOS/CMOS interfacing. Device performance is similar to MM74HCT but with ½ the output current drive of HC/HCT. ■ Space saving SOT23 or SC70 5-lead package ■ Ultra small MIcroPak leadless package ■ High Speed; tPD <7 ns typ, VCC = 5V, CL = 15 pF ■ Low Quiescent Power; ICC <1 µA typ, VCC = 5.5V ■ Balanced Output Drive; 2 mA IOL, −2 mA IOH ■ TTL-compatible inputs Ordering Code: Order Package Product Code Number Number Top Mark NC7ST32M5X MA05B 8S32 NC7ST32P5X MAA05A T32 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7ST32L6X MAC06A D7 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Package Description Supplied As 5-Lead SOT23, JEDEC MO-178, 1.6mm Logic Symbol 3k Units on Tape and Reel Connection Diagrams IEEE/IEC Pin Assignments for SOT23 and SC70 Pin Descriptions Pin Names Description A, B Inputs Y Output NC No Connect (Top View) Pad Assignments for MicroPak Function Table Y=A+B Inputs Output A B L L Y L L H H H L H H H H (Top Thru View) H = HIGH Logic Level L = LOW Logic Level TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.

The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of circuits outside the databook specifications.

(See Figure 2.) CPD is related to ICCD dynamic operating current by the expression: ICCD = (C PD) (VCC) (fIN) + (ICCstatic).
