74HCT253

74HC253; 74HCT253 Dual 4-input multiplexer; 3-state Rev. 9 — 20 October 2022 Product data sheet 1. General description The 74HC253; 74HCT253 is a dual 4-bit multiplexer, each with four binary inputs (nI0 to nI3), an output enable input (nOE) and shared select inputs (S0 and S1). One of the four binary inputs is selected by the select inputs and routed to the output nY. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits Non-inverting data path 3-state outputs interface directly with system bus Common select inputs Separate output enable inputs Wide supply voltage range from 2.0 V to 6.0 V Input levels: For 74HC253: CMOS level For 74HCT253: TTL level CMOS low power dissipation High noise immunity Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) ESD protection: HBM JESD22-A114F exceeds 2 kV MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3.
