16-Bit Registered Transceiver

Features

Functional Description

• Low power, pin-compatible replacement for LCX and

LPT families

• 5V tolerant inputs and outputs

The CY74FCT163646 16-bit transceiver is a three-state,

D-type register, 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 a HIGH logic

level. Output Enable (OE) and direction pins (DIR) are

provided to control the transceiver function. In the transceiver

mode, data present at the high impedance port may be stored

in either the A or B register, or in both. The select controls can

multiplex stored and real-time (transparent mode) data. The

direction control determines which bus will receive data when

the Output Enable (OE) is Active LOW. In the isolation mode

(Output Enable (OE) HIGH), A data may be stored in the B

• 24 mA balanced drive outputs

• Power-off disable outputs permits live insertion

• Edge-rate control circuitry for reduced noise

• FCT-C speed at 5.4 ns

• Latch-up performance exceeds JEDEC standard no. 17

• ESD > 2000V per MIL-STD-883D, Method 3015

• Typical output skew < 250 ps

• Industrial temperature range of –40˚C to +85˚C

• TSSOP (19.6-mil pitch) or SSOP (25-mil pitch)

• Typical V_olp(ground bounce) performance exceeds Mil

Std 883D

• V_CC= 2.7V to 3.6V

The CY74FCT163646 has 24-mA balanced output drivers

with current limiting resistors in the outputs. This reduces the

need for external terminating resistors and provides for

minimal undershoot and reduced ground bounce. The inputs

and outputs were designed to be capable of being driven by

5.0V buses, allowing them to be used in mixed voltage

systems as translators. The outputs are also designed with a

power-off disable feature enabling them to be used in

applications requiring live insertion.
