ON MC74LVX138M 3-to-8 line decoder with 5v−tolerant input Datasheet

MC74LVX138
3−to−8 Line Decoder
With 5V−Tolerant Inputs
The MC74LVX138 is an advanced high speed CMOS 3−to−8 line
decoder. The inputs tolerate voltages up to 7.0 V, allowing the
interface of 5.0 V systems to 3.0 V systems.
When the device is enabled, three Binary Select inputs (A0 − A2)
determine which one of the outputs (O0 − O7) will go Low. When
enable input E3 is held Low or either E2 or E1 is held High, decoding
function is inhibited and all outputs go high. E3, E2, and E1 inputs are
provided to ease cascade connection and for use as an address decoder
for memory systems.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter
guaranteed by design.

2. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC . CPD is used to determine the no−load dynamic
power consumption; PD = CPD VCC2 fin + ICC VCC.
