1 / 11 page  M54/M74HCT367 M54/M74HCT368 February 1993 HCT367 NON INVERTING, HCT368 INVERTING HEX BUS BUFFER (3-STATE) B1R (Plastic Package) ORDER CODES : M54HCTXXXF1R M74HCTXXXM1R M74HCTXXXB1R M74HCTXXXC1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) HCT368 HCT367 DESCRIPTION . HIGH SPEED tPD = 11 ns (TYP.) AT VCC =5 V . LOW POWER DISSIPATION ICC =4 µA (MAX.) AT TA =25 °C . COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) . OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH|= IOL = 6 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH =tPHL . PIN AND FUNCTION COMPATIBLE WITH 54/74LS367/368 The M54/74HCT367 and the M54/74HCT368 are high speed CMOS HEX BUS BUFFER (3-STATE) fabricated in silicon gate C 2MOS technology. They have the same high speed performance of LSTTL combined 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 (HCT367) and inverting outputs (HCT368). All inputs are equipped with protection circuits against static discharge and transient excess volt- age. This integrated circuit has input and output charac- teristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC 2MOS systems with TTL and NMOS components. They are also plug in replace- ments for LSTTL devices giving a reduction of power consumption. All inputs are equipped with protection circuits against static discharge and transient excess volt- age. 1/11 |
