description/ordering information

The SN65C1164 and SN75C1154 are low-power BiMOS devices containing four independent drivers and

receivers that are used to interface data terminal equipment (DTE) with data circuit-terminating equipment

(DCE). These devices are designed to conform to TIA/EIA-232-F. The drivers and receivers of the SN65C1154

and SN75C1154 are similar to those of the SN75C188 quadruple driver and SN75C189A quadruple receiver,

respectively. The drivers have a controlled output slew rate that is limited to a maximum of 30 V/μs and the

receivers have filters that reject input noise pulses of shorter than 1 μs. Both these features eliminate the need

for external components.

The SN65C1154 and SN75C1154 have been designed using low-power techniques in a BiMOS technology.

In most applications, the receivers contained in these devices interface to single inputs of peripheral devices

such as ACEs, UARTs, or microprocessors. By using sampling, such peripheral devices usually are insensitive

to the transition times of the input signals. If this is not the case, or for other uses, it is recommended that the

SN65C1154 and SN75C1154 receiver outputs be buffered by single Schmitt input gates or single gates of the

HCMOS, ALS, or 74F logic families.
