74LVTH16646
Low Voltage 16-Bit Transceiver/Register
with 3-STATE Outputs
General Description
The LVTH16646 contains sixteen non-inverting bidirec-
tional registered bus transceivers providing multiplexed
transmission of data directly from the input bus or from the
internal storage registers. Each byte has separate control
inputs which can be shorted together for full 16-bit opera-
tion. The DIR inputs determine the direction of data flow
through the device. The CPAB and CPBA inputs load data
into the registers on the LOW-to-HIGH transition (see
Functional Description).
The LVTH16646 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These transceivers are designed for low-voltage (3.3V)
VCC applications, but with the capability to provide a TTL
interface to a 5V environment. The LVTH16646 is fabri-
cated with an advanced BiCMOS technology to achieve
high speed operation similar to 5V ABT while maintaining
low power dissipation.
Features
s Input and output interface capability to systems at
5V VCC
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs
s Live insertion/extraction permitted
s Power Up/Down high impedance provides
glitch-free bus loading
s Outputs source/sink −32 mA/+64 mA
s Functionally compatible with the 74 series 16646
s Latch-up performance exceeds 500 mA

Note 9: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH).
