1 / 11 page  M54/M74HC367 M54/M74HC368 October 1992 HC367 NON INVERTING, HC368 INVERTING HEX BUS BUFFER (3-STATE) B1R (Plastic Package) ORDER CODES : M54HCXXXF1R M74HCXXXM1R M74HCXXXB1R M74HCXXXC1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) HC368 HC367 DESCRIPTION . HIGH SPEED tPD = 11 ns (TYP.) AT VCC =5 V . LOW POWER DISSIPATION ICC =4 µA (MAX.) AT TA =25 °C . HIGH NOISE IMMUNITY VNIH =VNIL =28 % VCC (MIN.) . OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH|= IOL = 6 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH =tPHL . WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V . PIN AND FUNCTION COMPATIBLE WITH 54/74LS367/368 The M54/74HC367 and the M54/74HC368 are 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 G1 and/or G2 inputs are held low, and when held high these outputs are disabled to be high-impedance. These outputs are capable of driving up to 15 LSTTL loads. The designer has a choice of non-inverting outputs (HC367) and inverting outputs (HC368). All inputs are equipped with protection circuits against static discharge and transient excess volt- age. 1/11 |
