1 / 11 page ![]() M54/74HC266 M54/74HC7266 March 1993 HC7266 QUAD EXCLUSIVE NOR GATE HC266 QUAD EXCLUSIVE NOR GATE WITH OPEN DRAIN B1R (Plastic Package) ORDER CODES : M54HCXXXF1R M74HCXXX1R M74HCXXXB1R M74HCXXXC1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) NC = No Internal Connection DESCRIPTION . HIGH SPEED tPD = 10 ns (TYP.) AT VCC =5 V . LOW POWER DISSIPATION ICC =1 µA (MAX.) AT TA =25 °C . HIGH NOISE IMMUNITY VNIH =VNIL =28 % VCC (MIN.) . OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE (7266) |IOH|= IOL = 4 mA (MIN.) . BALANCED PROPAGATION DELAYS (7266) tPLH =tPHL . WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V . PIN AND FUNCTION COMPATIBLE WITH 54/74LS7266 The M54/74HC266/7266 are high speed CMOS QUAD EXCLUSIVE NOR GATES, fabricated in sili- con gate C 2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The HC266 has a high performance N-channel MOS transistor (OPEN DRAIN output). The HC7266 has an output buffer which is CMOS structure. Input and output buffers ensure high noise immunity and stable outputs. All inputs are equipped with protection circuits against static discharge and transient excess volt- age. 1/11 |
