PIN AND FUNCTION COMPATIBLE WITH 54/74LS367/368

The M54/74HC367and the M54/74HC368are high

speed CMOS HEX BUS BUFFER (3-STATE)fabri-cated in silicon gate C 2MOS technology.They have the same high speed performance of LSTTL com-bined with true CMOS low power consumption.These devices contain six buffers,four buffers are controlled by an enable input (G1)and the other two buffers are controlled by the other enable input (G2);the outputs of each buffer group are enabled when G1and/or G2inputs are held low,and when held high these outputs are disabled to be high-impedance.

These outputs are capable of driving upto 15LSTTL loads.The designer has a choice of non-inverting outputs (HC367)and inverting outputs (HC368).All inputs are equipp ed with protection circuits against static discharge and transient excess volt-age.

(*)C PD is defined as the value of the IC’s internal equivalent capac itanc e which is calculated from the operating current con sump tion without load. (Refer to Test Circuit).Average operting current can be obtained by the following equ ation.I CC(opr)=C PD?V CC?f IN+I CC/6(per Channel)

TEST CIRCUIT I CC(Opr.)

INPUT WAVEFORM IS THE SAME AS THAT IN CASE OF SWITCHING CHARACTERISTICS TEST.C PD CALCULATION

C P

D is to be calculated with the following

formula by using the measured value of

I CC(opr.)in the test circuit opposite.

C PD=

I CC(opr)

f IN×V CC

In determining the typical value of C PD,a

relatively high frequency of1MHz was ap-

plied to f IN,in order to eliminate any error

caused by the quiescent supply current.
