M74HC280YRM13TR

M74HC280 9-bit parity generator Datasheet - production data • Pin and function compatible with 74 series 280 • ESD performance – HBM: 2 kV – MM: 200 V – CDM: 1 kV SO14 TSSOP14 Description The M74HC280 is a high-speed CMOS 9-bit parity generator fabricated with silicon gate C2MOS technology. Features It is composed of nine data inputs (A to I) and odd/even parity outputs (ΣODD and ΣEVEN). The nine data inputs control the output conditions. When the number of high-level inputs is odd, ΣODD outputs are kept high and ΣEVEN outputs are kept low. Conversely, when the number of high-level outputs is even, ΣEVEN outputs are kept high and ΣODD outputs are kept low. The IC generates either odd or even parity making the application flexible. The word-length capability is easily expanded by cascading. • High-speed: tPD = 22 ns (typ.) at VCC = 6 V • Low power dissipation: ICC = 4 μA (max.) at TA = 25 °C • High noise immunity: VNIH = VNIH = 28 % VCC (min) • Symmetrical output impedance: |IOH| = IOL = 4 mA (min.) • Balanced propagation delays: tPLH ≅ tPHL All inputs are equipped with protection circuits against static discharge and transient excess voltage. • Wide operating voltage range: VCC (opr) = 2 V to 6 V Table 1.

CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load (refer to test circuit). Average operating current can be obtained by the following equation: ICC(opr) = CPD x VCC x fIN + ICC. Figure 4. Test circuit GAMS0301141630CB 1.
