Description
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Analog Multiplexers/ Demultiplexers MC54/74HC4051A MC74HC4052A MC54/74HC4053A High–Performance Silicon–Gate CMOS The MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A utilize silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/ demultiplexers control analog voltages that may vary across the complete power supply range (from VCC to VEE). The HC4051A, HC4052A and HC4053A are identical in pinout to the metal–gate MC14051AB, MC14052AB and MC14053AB. The Channel–Select inputs determine which one of the Analog Inputs/Outputs is to be connected, by means of an analog switch, to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off. The Channel–Select and Enable inputs are compatible with standard CMOS outputs; with pullup resistors they are compatible with LSTTL outputs. These devices have been designed so that the ON resistance (Ron) is more linear over input voltage than R on of metal–gate CMOS analog switches. For a multiplexer/demultiplexer with channel–select latches, see HC4351A. • Fast Switching and Propagation Speeds • Low Crosstalk Between Switches • Diode Protection on All Inputs/Outputs • Analog Power Supply Range (VCC – VEE) = 2.0 to 12.0 V • Digital (Control) Power Supply Range (VCC – GND) = 2.0 to 6.0 V • Improved Linearity and Lower ON Resistance Than Metal–Gate Counterparts • Low Noise • In Compliance With the Requirements of JEDEC Standard No. 7A • Chip Complexity: HC4051A — 184 FETs or 46 Equivalent Gates HC4052A — 168 FETs or 42 Equivalent Gates HC4053A — 156 FETs or 39 Equivalent Gates LOGIC DIAGRAM MC54/74HC4051A Single–Pole, 8–Position Plus Common Off X0 14 X1 15 X2 ANALOG 12 MULTIPLEXER/ INPUTS/ X3 DEMULTIPLEXER OUTPUTS X4 1 5 X5 2 X6 4 X7 11 A CHANNEL 10 B SELECT 9 INPUTS C 6 ENABLE PIN 16 = VCC PIN 7 = VEE PIN 8 = GND 13 16 1 J SUFFIX CERAMIC PACKAGE CASE 620–10 N SUFFIX PLASTIC PACKAGE CASE 648–08 D SUFFIX SOIC PACKAGE CASE 751B–05 DW SUFFIX SOIC WIDE PACKAGE CASE 751G–02 DT SUFFIX TSSOP PACKAGE CASE 948F–01 16 1 16 1 16 1 16 1 ORDERING INFORMATION MC54HCXXXXAJ MC74HCXXXXAN MC74HCXXXXAD MC74HCXXXXADW MC74HCXXXXADT Ceramic Plastic SOIC SOIC Wide TSSOP FUNCTION TABLE – MC54/74HC4051A Control Inputs Enable L L L L L L L L H C L L L L H H H H X Select B A L L H H L L H H X L H L H L H L H X ON Channels X0 X1 X2 X3 X4 X5 X6 X7 NONE X = Don’t Care 3 X COMMON OUTPUT/ INPUT Pinout: MC54/74HC4051A (Top View) VCC 16 X2 15 X1 14 X0 13 X3 12 A 11 B 10 C 9 1 X4 2 X6 3 X 4 X7 5 X5 6 7 8 GND Enable VEE This document contains information on a new product.
