| MC54/74F352 DUAL 4-INPUT MULTIPLEXER The MC54/74F352 is a very high speed dual 4-input multiplexer with common Select inputs and individual Enable inputs for each section. It can select two bits of data from four sources. The two buffered outputs present data in the inverted (complementary) form. The F352 is the functional equivalent of the F153 except with inverted outputs. * Inverted Version of the F153 * Separate Enables for Each Multiplexer * Input Clamp Diode Limits High-Speed Termination Effects CONNECTION DIAGRAM (TOP VIEW) VCC 16 Eb 15 S0 14 I3b 13 I2b 12 I1b 11 I0b 10 Zb 9 16 1 DUAL 4-INPUT MULTIPLEXER FASTTM SCHOTTKY TTL J SUFFIX CERAMIC CASE 620-09 1 Ea 2 S1 3 I3a 4 I2a 5 I1a 6 I0a 7 Za 8 GND 16 1 N SUFFIX PLASTIC CASE 648-08 LOGIC DIAGRAM Ea I0a I1a I2a I3a S1 S0 I0b I1b I2b I3b Eb 16 1 D SUFFIX SOIC CASE 751B-03 ORDERING INFORMATION MC54FXXXJ MC74FXXXN MC74FXXXD Ceramic Plastic SOIC LOGIC SYMBOL 2 S1 14 S0 Ea I0a I1a I2a I3a I0b I1b I2b I3b Eb 1 6 5 4 3 10 11 12 13 15 7 Za Za Zb 9 VCC = PIN 14 GND = PIN 7 Zb FAST AND LS TTL DATA 4-157 MC54/74F352 GUARANTEED OPERATING RANGES Symbol VCC TA Supply Voltage Operating Ambient Temperature Range Parameter 54, 74 54 74 IOH IOL Output Current -- High Output Current -- Low 54, 74 54, 74 Min 4.5 - 55 0 Typ 5.0 25 25 Max 5.5 125 70 -1.0 20 Unit V C mA mA FUNCTIONAL DESCRIPTION The F352 is a dual 4-input multiplexer. It selects two bits of data from up to four sources under the control of the common Select inputs (S0, S1).The two 4-input multiplexer circuits have individual active-LOW Enables(Ea, Eb) which can be used to strobe the outputs independently. When the Enables (Ea, Eb) are HIGH, the corresponding outputs (Za, Zb) are forced HIGH. The logic equations for the outputs are shown below: The F352 can be used to move data from a group of registers to a common output bus. The particular register from which the data came would be determined by the state of the Select inputs. A less obvious application is as a function generator. The F352 can generate two functions of three variables. This is useful for implementing highly irregular random logic. Za = Ea * (I0a * S1 * S0 + I1a * S1 * S0 + I2a * S1 * S0 + I3a * S1 * S0) Zb = Eb * (I0b * S1 * S0 + I1b * S1 * S0 + I2b * S1 * S0 + I3b * S1 * S0) FUNCTION TABLE Select Inputs S0 X L L H H L L H H S1 X L L L L H H H H E H L L L L L L L L Inputs (a or b) I0 X L H X X X X X X I1 X X X L H X X X X I2 X X X X X L H X X I3 X X X X X X X L H Output Z H H L H L H L H L H = HIGH Voltage Level L = LOW Voltage Level X = Don't Care FAST AND LS TTL DATA 4-158 MC54/74F352 DC CHARACTERISTICS OVER OPERATING TEMPERATURE RANGE (unless otherwise specified) Limits Symbol VIH VIL VIK VOH Parameter Input HIGH Voltage Input LOW Voltage Input Clamp Diode Voltage Output HIGH Voltage 54, 74 74 VOL IIH Output LOW Voltage Input HIGH Current 2.5 2.7 3.4 3.4 0.35 0.5 20 100 IIL IOS ICCH ICCL Input LOW Current Output Short Circuit Current (Note 2) Power Supply Current -60 9.3 13.3 -0.6 -150 14 20 mA mA mA Min 2.0 0.8 -1.2 Typ Max Unit V V V V V V A Test Conditions Guaranteed Input HIGH Voltage Guaranteed Input LOW Voltage IIN = -18 mA IOH = -1.0 mA IOH = -1.0 mA IOL = 20 mA VIN = 2.7 V VIN = 7.0 V VIN = 0.5 V VOUT = 0 V VIN = GND VIN = HIGH VCC = MAX VCC = MAX VCC = MAX VCC = MIN VCC = 4.50 V VCC = 4.75 V VCC = MIN VCC = MAX NOTES: 1.
