74HC253

74HC253 Dual 4-Input Multiplexer with 3-State Outputs

The 74HC253 is a high-performance dual 4-bit multiplexer designed for reliable signal routing and data selection in electronic systems. Each of the two multiplexers features four binary inputs (nI0 to nI3), shared select inputs (S0 and S1), and individual output enable inputs (nOE), allowing precise control over which input signal is routed to the output. When the output enable is set HIGH, the outputs enter a high-impedance state, making this IC ideal for direct interface with system buses. With a wide supply voltage range of 2.0 V to 6.0 V and robust ESD protection, the 74HC253 is a dependable solution for arcade, pinball, and game room equipment repair and restoration projects.

Built to meet stringent JEDEC standards and rated for operation across a broad temperature range, this component delivers consistent CMOS-level performance with low power dissipation — a trusted choice for technicians maintaining and upgrading classic and modern game room machines.
