IDT74LVC157A 3.3V CMOS QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR EXTENDED COMMERCIAL TEMPERATURE RANGE 3.3V CMOS QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/MULTIPLEXER, 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: – – – – – – – – – – IDT74LVC157A 0.5 MICRON CMOS Technology ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) 1.27mm pitch SOIC, 0.635mm pitch QSOP, 0.65mm pitch SSOP, 0.65mm pitch TSSOP packages Extended commercial range of – 40°C to +85°C VCC = 3.3V ±0.3V, Normal Range VCC = 2.3V to 3.6V, Extended Range CMOS power levels (0.4µ W typ. static) Rail-to-Rail output swing for increased noise margin All inputs, outputs and I/O are 5 Volt tolerant Supports hot insertion This quadruple 2-line to 1-line data selector/multiplexer is built using advanced dual metal CMOS technology. The LVC157A features a common strobe (G) input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The device provides true data. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVC157A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. APPLICATIONS: Drive Features for LVC157A: – High Output Drivers: ±24mA – Reduced system switching noise • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1A 2 4 1B 2A 3 5 7 2B 1Y 6 2Y 11 3A 9 3B 4A 10 14 12 4B G A/B 3Y 13 4Y 15 1 EXTENDED COMMERCIAL TEMPERATURE RANGE FEBRUARY 2000 1 c 1999 Integrated Device Technology, Inc.
