74HC/HCT7080

The 74HC/HCT7080 are 16-bit parity generators or

checkers commonly used to detect errors in high-speed

data transmission or data retrieval systems.

FEATURES

• Word-length easily expanded by cascading

• Generates either even or odd parity for 16-data bits

• Output capability: standard

The even and odd parity output is available for generating

or checking even/odd parity up to 16-bits.

• I_CCcategory: MSI

The even/odd parity output (E/O) is HIGH when an even

number of data inputs (I₀to I₁₅) are HIGH and the

cascade/even-odd-changing input (X) is HIGH.

GENERAL DESCRIPTION

The 74HC/HCT7080 are high-speed Si-gate CMOS

devices. They are specified in compliance with JEDEC

standard no. 7A.

Expansion to larger word sizes is accomplished by

connecting the even/odd parity output (E/O) to the

cascade/even-odd-changing input (X) of the final stage.

Notes

1. C_PDis used to determine the dynamic power dissipation (P_Din µW):

P_D= C_PD× V_CC²× f_i+ ∑ (C_L×V_CC²× f_o) where:

f_i= input frequency in MHz

f_o= output frequency in MHz

∑ (C_L× V_CC²× f_o) = sum of outputs

C_L= output load capacitance in pF

V_CC= supply voltage in V

2. For HC the condition is V_I= GND to V_CC

For HCT the condition is V_I= GND to V_CC− 1.5 V
