NXP 74HCT158 Quad 2-Input Multiplexer
The NXP 74HCT158 is a high-speed Si-gate CMOS device that is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. This integrated circuit is a versatile component designed for use in digital systems where data selection and routing are essential. The 74HCT158 is a quad 2-input multiplexer that allows the selection of data from two sources for each multiplexer via common select inputs.
The 74HCT158 features four identical 2-input multiplexers with separate output-enable (OE) inputs. Each multiplexer has two data inputs (I0, I1), one output (Y), and one common select input (S). The data on the selected input is passed to the output when the output-enable (OE) input is at a low logic level. When OE is high, the output is in the high-impedance state, effectively disconnecting the output from the circuit. This feature allows for the use of these devices in bus-oriented systems.
With its wide operating voltage range of 4.5V to 5.5V and the ability to interface with TTL levels, the 74HCT158 is suitable for a variety of applications including signal gating, data routing, and multiplexing. Its low power consumption and high noise immunity of CMOS combined with the speed of LSTTL make it a robust choice for high-speed data management tasks in complex digital systems.
