Overview
MM54HCT151 MM74HCT151 8-Channel Digital Multiplexer November 1995 MM54HCT151 MM74HCT151 8-Channel Digital Multiplexer General Description This high speed Digital multiplexer utilizes advanced silicongate CMOS technology Along with the high noise immunity and low power dissipation of standard CMOS integrated circuits it possesses the ability to drive 10 LS-TTL loads The MM54HCT151 MM74HCT151 selects one of the 8 data sources depending on the address presented on the A B and C inputs It features both true (Y) and complement (W) outputs The STROBE input must be at a low logic level to enable this multiplexer A high logic level at the STROBE forces the W output high and the Y output low MM54HCT MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices These parts are also plug-in replacements for LSTTL devices and can be used to reduce power consumption in existing designs Features Y Y Y Y Y Typical propagation delay 20 ns Low quiescent supply current 40 mA maximum (74HCT Series) Low input current 1 mA maximum Fanout of 10 LS-TTL loads TTL input compatible Connection and Logic Diagrams Dual-In-Line Package Truth Table Inputs C X L L L L H H H H Select B X L L H H L L H H A X L H L H L H L H Strobe S H L L L L L L L L Outputs Y L D D D D D D D D W H D D D D D D D D TL F 9399 – 1 H e High Level L e Low Level X e Don’t Care D0 D1 D7 e the level of the respective D input Top View Order Number MM54HCT151 or MM74HCT151 TL F 9399 – 2 C1995 National Semiconductor Corporation TL F 9399 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Notes 1 2) Operating Conditions Supply Voltage (VCC) DC Input or Output Voltage (VIN VOUT) Operating Temp Range (TA) MM74HCT MM54HCT Input Rise or Fall Times (tr tf) Min 45 0 Max 55 VCC Units V V If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications b 0 5V to a 7 0V Supply Voltage (V...
