Product data sheet
1. General description
The 74LVC157A is a quad 2-input multiplexer. The device features select (S) and enable E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the outputs (1Y to 4Y) LOW. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V applications.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
2. Features and benefits
• Overvoltage tolerant inputs to 5.5 V • Wide supply voltage range from 1.2 V to 3.6 V • CMOS low power consumption • Direct interface with TTL levels • Complies with JEDEC standard: • • JESD8-7A (1.65 V to 1.
