74LVTH652
Low Voltage Octal Transceiver/Register
with 3-STATE Outputs
General Description
The LVTH652 consists of bus transceiver circuits with D-
type flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the input bus or from the
internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes to HIGH
logic level. Output Enable pins (OEAB, OEBA) are pro-
vided to control the transceiver function. (See Functional
Description).
The LVTH652 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
This octal transceiver/register is designed for low-voltage
(3.3V) V_CC applications, but with the capability to provide a
TTL interface to a 5V environment. The LVTH652 is fabri-
cated with an advanced BiCMOS technology to achieve
high speed operation similar to 5V ABT while maintaining
low power dissipation.
