Description
The Intersil HS-3374RH is a radiation hardened 8-bit
bidirectional level converter designed to interface CMOS logic
levels with TTL logic levels in radiation hardened bus oriented
systems. The HS-3374RH is fabricated using a radiation
hardened EPI-CMOS process and features eight parallel
bidirectional buffer/level converters.
Two control inputs, ENABLE and DISABLE, are used to deter-
mine the direction of data flow, and to set both the in puts and
outputs in the high impedance state. The control inputs may be
driven by either TTL or CMOS logic drivers capable of sinking
one standard TTL load.
The HS-3374RH is a non-inverting version of the industry
standard CD40116. The non-inverting outputs of the
HS-3374RH reduce PC board chip count by eliminating the
need to restore data back to a non-inverted format.
NOTE:
1. For operation at 10V and transient levels above 1 x 10

High Impedance (Z)
0 = Low Level 1 = High Level X = Don’t Care
Z = High Impedance on Both CMOS and TTL sides.
NOTE: An important caveat that is applicable to CMOS devices in
general is that unused inputs should never be left floating. 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-3374RH pins: A0 - 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 three-state 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.
* WARNING: Do not activate the Disable input by hardwiring to any
TTL input pins. This is an incorrect mode of operation.
