HS-82C08RH TM Data Sheet August 2000 File Number Radiation Hardened 8-Bit Bus Transceiver Features The Intersil HS-82C08RH is a radiation-hardened octal bus transceiver with three-state outputs. It is manufactured using a self-aligned, junction isolated CMOS process and is designed for use with the HS-80C08RH radiation-hardened microprocessor. The HS-82C08RH allows asynchronous two-way communication between data buses. The direction of data flow is determined by the logic level on the transmit/receive (T/R) input. A logic high on the T/R input specifies data flow from Port A to Port B of the device. Conversely, a logic low on the T/R input specifies data flow from Port B to Port A. The Output Enable input disables both ports by placing them in the high impedance state. • Electrically Screened to SMD # 5962-95714 The HS-82C08RH is ideally suited for a wide variety of buffering applications in radiation-hardened microcomputer systems. • Electrically Equivalent to Sandia SA2997 Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-95714.

This rule applies to inputs connected to a three-state bus. The need for external pull-up resistors during three-state bus conditions is eliminated by the presence of regenerative latches on the following HS-82C08RH pins. A0-7 and B0-7 The functional block diagram depicts one of these pins with the regenerative latch. When the CMOS driver assumes the high impedance state, the latch holds the bus in whatever logic state (high or low) it was before the threestate condition. A transient drive current of ±1.5mA at VDD/2 ±0.5V for 10ns is required to switch the latch. Thus, CMOS device inputs connected to the bus are not allowed to float during three-state conditions. 2 HS-82C08RH Switching Time Waveforms tr INPUT AN OR BN OUTPUT BN OR AN VDD 0V tf 0.5VDD 0.5VDD tPLH VDD DEVICE UNDER TEST tPHL 0.5VDD 0.5VDD TEST POINTS CL (NOTE) 0V tr = tf ≤ 20ns 10% TO 90% NOTE: CL includes stray and jig capacitance.
